Investigation of culture heterogeneity of the hydrogen-oxidizing bacterium Alcaligenes eutrophus / G. N. Stasishina [et al.] // Microbiology. - 1999. - Vol. 68, Is. 2. - P164-170 . - ISSN 0026-2617

Аннотация: Some morphological, physiological, and biochemical manifestations of heterogeneity in the population of the hydrogen-oxidizing bacterium Alcaligenes eutrophus Z1 were studied. The population dissociated into R and S variants differing in the size, appearance, and architectonics of colonies, cell ultrastructure, growth rate, enzyme activity, and chemical composition. Heterogeneity also manifested itself in different responses of cells to antibiotics, surfactants, and elevated temperature. В© 1999 MAHK "Hayka/Interperiodica".

Аннотация: The intrinsic fluorescence of two apo-photoproteins has been characterized and its concentration-dependent quenching by coelenterazine has been for the first time applied to determine the apparent dissociation constants for coelenterazine binding with apo-aequorin (1.2 +/- 0.12 mu M) and apo-obelin (0.2 +/- 0.04 mu M). Stopped-flow measurements of fluorescence quenching showed that coelenterazine binding is a millisecond-scale process, in contrast to the formation of an active photoprotein complex taking several hours. This finding evidently shows that the rate-limiting step of active photoprotein formation is the conversion of coelenterazine into its 2-hydroperoxy derivative.

Green flavoprotein from P. leiognathi: purification, characterization and identification as the product of the lux G(N) gene / A. A. Raibekas // Journal of bioluminescence and chemiluminescence. - 1991. - Vol. 6, Is. 3. - P. 169-176 . - ISSN 0884-3996

Аннотация: A green flavoprotein (GFP) was isolated and purified to homogeneity from Photobacterium leiognathi, strain 208. GFP is a homodimer of molecular weight 54,000 and contains two molecules of an unusual flavin per molecule of protein. Various biochemical characteristics including isoelectric point, trypsin and chymotrypsin degradation, SDS and temperature influence on subunit dissociation and the dissociation of the flavin chromophore, were investigated. The sequence of 23 N-terminal amino acids was determined and found to be concurrent with the N-terminal amino acid sequence encoded by the lux G(N) gene of P. leiognathi. This fact suggests that GFP is a structural component of the Photobacterium luminescence system.

NAD(P)H:FMN-Oxidoreductase Functioning Under Macromolecular Crowding: In Vitro Modeling / A. E. Govorun, E. N. Esimbekova, V. A. Kratasyuk // Doklad. Biochem. Biophys. - 2019. - Vol. 486, Is. 1. - P213-215, DOI 10.1134/S160767291903013X . - ISSN 1607-6729
Аннотация: The functioning of NAD(P)H:FMN‑oxidoreductase (Red) from Vibrio fischeri under conditions of macromolecular crowding (MMC) simulated in vitro by adding biopolymers (starch and gelatin) was studied. The dissociation rate constants and the activation energies of dissociation of Red to the subunits were calculated, and the process of denaturation of Red was analyzed. It is shown that the functioning of Red both under conditions of MMC and in diluted solutions is the same. This result refutes the common belief that the native conformation of enzymes in vivo is stabilized due to MMC as compared to the in vitro conditions. © 2019, Pleiades Publishing, Ltd.

The smallest isoform of Metridia longa luciferase as a fusion partner for hybrid proteins / M. D. Larionova, S. V. Markova, N. V. Tikunova, E. S. Vysotski // Int. J. Mol. Sci. - 2020. - Vol. 21, Is. 14. - Ст. 4971. - P1-16, DOI 10.3390/ijms21144971 . - ISSN 1661-6596

Аннотация: Bioluminescent proteins are widely used as reporter molecules in various in vitro and in vivo assays. The smallest isoform of Metridia luciferase (MLuc7) is a highly active, naturally secreted enzyme which, along with other luciferase isoforms, is responsible for the bright bioluminescence of marine copepod Metridia longa. In this study, we report the construction of two variants of a hybrid protein consisting of MLuc7 and 14D5a single-chain antibody to the surface glycoprotein E of tick-borne encephalitis virus as a model fusion partner. We demonstrate that, whereas fusion of a single-chain antibody to either N-or C-terminus of MLuc7 does not affect its bioluminescence properties, the binding site on the single-chain antibody influences its binding capacity. The affinity of 14D5a-MLuc7 hybrid protein (KD = 36.2 nM) where the C-terminus of the single-chain antibody was fused to the N-terminus of MLuc7, appeared to be 2.5-fold higher than that of the reverse, MLuc7-14D5a (KD = 87.6 nM). The detection limit of 14D5a-MLuc7 hybrid protein was estimated to be 45 pg of the recombinant glycoprotein E. Although the smallest isoform of M. longa luciferase was tested as a fusion partner only with a single-chain antibody, it is reasonable to suppose that MLuc7 can also be successfully used as a partner for genetic fusion with other proteins. © 2020 by the authors.
