Аннотация: The temperature dependence of bioluminescent activity of the Ca2+-activated photoprotein obelin from the hydroid polyp Obelia longissima and thermoinactivation of this protein at different concentrations of (NH4)2SO4 have been studied. The maximal intensity of luminescence of obelin was observed at 4-15-degrees-C. The activity of the photoprotein is completely stable to storage for 3 days at room temperature. Increasing the temperature to 40-degrees-C resulted in a 25-30% loss of enzyme activity in 1 h. The presence of ammonium sulfate during heating stabilizes the activity of obelin. Two breaks, at 11 +/- 3-degrees-C and 47 +/- 3-degrees-C, are observed in the Arrhenius plot of the first-order rate constant of the luminescence decay. The bioluminescent curves of obelin are biphasic in the temperature range 10-40-degrees-C. It is assumed that obelin may exist in two kinetically distinct conformers (active and inactive) whose ratio is temperature dependent.

Ключевые слова (''Своб.индексиров.''): bioluminescence--luciferase--nadh, fmn-oxidoreductase--immobilization
Аннотация: A gel model for the functioning of luciferase in cells has been constructed using bacterial NADH:FMN-oxidoreductase and luciferase immobilized in starch gel disks. The characteristics of the immobilized luciferase depend on the duration of drying, the amount and concentration of the gel, the nature of the support used for drying, and the properties of the initial enzyme preparation. Functionally important enzyme groups remain intact in the immobilized preparation, and luciferase retains its high specificity with respect to aldehydes. The gel microenvironment appears to be optimal for luciferase, judging from its high activity and increased stability. Conditions allowing repeated use of the preparation have been found. The approach permits co-immobilization of luciferase with other enzymes and their substrates. The error in bioluminescence measurements using the disks is 5-10%. A procedure for stabilization of the immobilized luciferase during repeated use has been devised.

Ключевые слова (''Своб.индексиров.''): bacterial luciferase--temperature--activation energy
Аннотация: Effects of temperature on bioluminescent patterns of luciferases from luminescent bacteria Vibrio harveyi, Vibrio fischeri, Photobacterium leiognathi, and Photobacterium phosphoreum were studied. The highest luminescence level was observed at 15-25 degrees C for the luciferase from P. phosphoreum, at 20-30 degrees C for the V. fischeri and P. leiognathi enzymes, and at 30-37 degrees C for the enzyme from V. harveyi. All the luciferases were significantly stabilized at increased salt concentrations, at low pH values, or in the presence of dithiothreitol (DTT) and EDTA. The addition of DTT and EDTA affected the reversible stage of enzyme inactivation, while salts reduced the rate of the irreversible stage. A peak corresponding to aggregated protein was detected by gel chromatography of irreversibly inactivated luciferase. Activation energies were calculated for each luciferase in bioluminescent reactions with decanal, dodecanal, tetradecanal, and without aldehydes. The activation energy of the reaction with tetradecanal was much lower than those with the other aldehydes. The temperature dependence of the lifetime of the long-lived reaction intermediate showed that in the 10-30 degrees C interval all the luciferases, except for the enzyme from V. harveyi, have only one active form.

Заглавие : Interaction of Photobacterium leiognathi and Vibrio fischeri Y1 luciferases with fluorescent (antenna) proteins: Bioluminescence effects of the aliphatic additive
Место публикации : Biochemistry. - 1996. - Vol. 35, Is. 37. - С. 12086-12093. - ISSN 00062960 (ISSN) , DOI 10.1021/bi9608931

Аннотация: The kinetics of the bacterial bioluminescence reaction is altered in the presence of the fluorescent (antenna) proteins, lumazine protein (LumP) from Photobacterium or the yellow fluorescence proteins (YFP) having FMN or Rf bound, from Vibrio fischeri strain Y1. Depending on reaction conditions, the bioluminescence intensity and its decay rate may be either enhanced or strongly quenched in the presence of the fluorescent proteins. These effects can be simply explained on the basis of the same protein-protein complex model that accounts for the bioluminescence spectral shifts induced by these fluorescent proteins. In such a complex, where the fluorophore evidently is in proximity to the luciferase active site, it is expected that the on off rate of certain aliphatic components of the reaction should be altered with a consequent shift in the equilibria among the luciferase intermediates, as recently elaborated in a kinetic scheme. These aliphatic components are the bioluminescence reaction substrate, tetradecanal or other long-chain aldehyde, its carboxylic acid product, or dodecanol used as a stabilizer of the luciferase peroxyflavin. No evidence can be found for the protein- protein interaction in the absence of the aliphatic component.

Ключевые слова (''Своб.индексиров.''): biotest--bioluminescence--enzymes--environmental monitoring
Аннотация: The influence of several suites of pollutants (metallic salts, quinones, and phenols) on bacterial bioluminescence in vivo and in vitro (five test systems) was investigated. The sensitivity of bioluminescence to the different pollutants was evaluated, and inhibition constants were measured. The data obtained were shown to correlate with the physical and chemical characteristics of the substances and the structure of the bioluminescent systems. It has been found that three bioluminescent tests (water-soluble enzyme systems, immobilized enzyme systems, and bioluminescent bacteria) show higher sensitivity to pollutants and cover all types of widespread contamination. These tests were chosen as a set of bioluminescent assays for the detection of pollutants. (C) 1998 John Wiley & Sons, Inc.

Аннотация: The influence of xenobiotics on the bioluminescent enzyme system is considered in terms of molecular action on the primary physicochemical processes-energy, electron and hydrogen (e(-) + H+) transduction. Dyes, non-fluorescent chemically inert organic compounds, redox-active organic compounds and metallic salts were investigated. The influence of the different xenobiotics depends in a complex way on physicochemical characteristics of the xenobiotic molecules (spectral-luminescent characteristics, electron-acceptation energy and redox potential).

Аннотация: Scytalone dehydratase is a molecular target of inhibitor design efforts aimed at preventing the fungal disease caused by Magnaporthe grisea. A method for cocrystallization of enzyme with inhibitors at neutral pH has produced several crystal structures of enzyme-inhibitor complexes at resolutions ranging from 1.5 to 2.2 Angstrom Four high resolution structures of different enzyme-inhibitor complexes are described. In contrast to the original X-ray structure of the enzyme, the four new structures have well-defined electron density for the loop region comprising residues 115-119 and a different conformation between residues 154 and 160. The structure of the enzyme complex with an aminoquinazoline inhibitor showed that the inhibitor is in a position to form a hydrogen bond with the amide of the Asn131 side chain and with two water molecules in a fashion similar to the salicylamide inhibitor in the original structure, thus confirming design principles. The aminoquinazoline structure also allows for a more confident assignment of donors and accepters in the hydrogen bonding network, The structures of the enzyme complexes with two dichlorocyclopropane carboxamide inhibitors showed the two chlorine atoms nearly in plane with the amide side chain of Asn131. The positions of Phe53 and Phe158 are significantly altered in the new structures in comparison to the two structures obtained from crystals grown at acidic pH, The multiple structures help define the mobility of active site amino acids critical for catalysis and inhibitor binding.

Аннотация: A model for the spatial structure of firefly luciferase-ATP-luciferin complex is suggested using the coordinates of unliganded luciferase and the enzyme-substrate complex of the adenylating subunit of gramicidin S synthetase known from the literature. Conformational changes in luciferase can occur during substrate binding resulting in a relative orientation of two luciferase domains similar to that in case of the AMP-phenylalanine-synthetase complex. The model is consistent with data on the physicochemical properties of firefly luciferase and its complexes with the substrates.

Аннотация: Kinetics of the triple bioluminescent enzyme system: alcohol dehydrogenase - NADH:FMN-oxidoreductase - luciferase in the presence of quinones and phenols has been studied. The correspondence between the bioluminescent kinetic parameters, redox potentials and concentrations of the quinones and phenols has been estimated. The substances have been shown to change bioluminescent kinetics through moving off the NAD(+)/NADH balance in the enzyme processes. This system is proposed to be used as enzymatic biotest in ecological monitoring. (C) 1998 Elsevier Science Ltd. All rights reserved.

Аннотация: We describe our experience with laboratory courses in enzymology based on the phenomenon of bioluminescence. The soluble and immobilized enzymes of luminous bacteria are used and the practical enzymological course consists of four main courses: (1) training in measuring the activities of soluble and immobilized enzymes; (2) the investigation of kinetic characteristics (kinetic constants) and enzyme-substrate and enzyme-inhibitor interactions in the bacterial bioluminescent reaction; (3) The testing of physico-chemical characteristics of enzymes (pH, temperature, ion strength, etc.); (4) the effect of inhibitors on enzymes. Training is possible in groups of about ten persons. Our practice work has been introduced in the biological, pedagogical and physical departments of Krasnoyarsk State University. Students of the pedagogical department have created a popular and interesting series of laboratory works for high school children aged 14-17 years. Copyright (C) 1999 John Wiley & Sons, Ltd.

Аннотация: The effects of a number of quinones on the bioluminescence characteristics of a three-component enzymatic system containing alcohol dehydrogenase, bacterial luciferase, and NADH-FMN oxidoreductase were studied to find the most sensitive kinetic parameters of the system intended to be used in biological testing. Both direct and back reactions catalyzed by alcohol dehydrogenase were studied in the presence and in the absence of quinones. The kinetic parameters of the bioluminescent system were found to depend on the redox potentials and concentrations of quinones. The quinone-induced effects were shown to be associated with changes in the NAD(+)/NADH ratio in the chain of NADH-dependent enzymes, The three-enzyme system based on alcohol dehydrogenase is suggested as a bioluminescence test for ecological monitoring of waste water.
