Аннотация: Obelin from the hydroid Obelia longissima and aequorin are members of a subfamily of Ca2+-regulated photoproteins that is a part of the larger EF-hand calcium binding protein family. On the addition of Ca2+, obelin generates a blue bioluminescence emission (lambda(max) = 485 nm) as the result of the oxidative decarboxylation of the bound substrate, coelenterazine. The W92F obelin mutant is noteworthy because of the unusually high speed with which it responds to sudden changes of [Ca2+] and because it emits violet light rather than blue due to a prominent band with lambda(max) = 405 nm. Increase of pH in the range from 5.5 to 8.5 and using D2O both diminish the contribution of the 405 nm band, indicating that excited state proton transfer is involved. Fluorescence model studies have suggested the origin of the 485 nm emission as the excited state of an anion of coelenteramide, the bioluminescence reaction product, and 405 nm from the excited neutral state. Assuming that the dimensions of the substrate binding cavity do not change during the excited state formation, a His22 residue within hydrogen bonding distance to the 6-(p-hydroxy)-phenyl group of the excited coelenteramide is a likely candidate for accepting the phenol proton to produce an ion-pair excited state, in support of recent suggestions for the bioluminescence emitting state. The proton transfer could be impeded by removal of the Trp92 H-bond, resulting in strong enhancement of a 405 nm band giving the violet color of bioluminescence. Comparative analysis of 3D structures of the wild-type (WT) and W92F obelins reveals that there are structural displacements of certain key Ca2+-ligating residues in the loops of the two C-terminal EF hands as well as clear differences in hydrogen bond networks in W92F. For instance, the hydrogen bond between the side-chain oxygen atom of Asp 169 and the main-chain nitrogen of Arg112 binds together the incoming alpha-helix of loop III and the exiting cc-helix of loop IV in WT, providing probably concerted changes in these EF hands on calcium binding. But this linkage is not found in W92F obelin. These differences apparently do not change the overall affinity to calcium of W92F obelin but may account for the kinetic differences between the WT and mutant obelins. From analysis of the hydrogen bond network in the coelenterazine binding cavity, it is proposed that the trigger for bioluminescence reaction in these Ca2+-regulated photoproteins may be a shift of the hydrogen bond donor-acceptor separations around the coelenterazine-2-hydroperoxy substrate, initiated by small spatial adjustment of the exiting a-helix of loop IV.

Ca(2+)-regulated photoprotein -- bioluminescence -- dual-color assay
Аннотация: Two kinds of Ca(2+)-regulated photoprotein obelin with altered color of bioluminescence were obtained by active-center amino acid substitution. The mutant W92F-H22E emits violet light (lambda(max)=390 nm) and the mutant Y139F emits greenish light (lambda (max)=498 nm), with small spectral overlap, both display high activity and stability and thus may be used as reporters. For demonstration, the mutants were applied in dual-color simultaneous immunoassay of two gonadotropic hormones-follicle-stimulating hormone and luteinizing hormone. Bioluminescence of the reporters was simultaneously triggered by single injection of Ca(2+) solution, divided using band-pass optical filters and measured with a two-channel photometer. The sensitivity of simultaneous bioluminescence assay was close to that of a separate radioimmunoassay.

Аннотация: Obelin is a photoprotein that emits light by Ca2+-binding. To develop a bioluminescent immunoassay based on the light emission property of obelin, we have expressed the apoobelin fusion protein with ZZ-domain of S. aureus protein A in E. coil by recombinant DNA techniques. The pro2Z-obelin expressed was purified by one-step affinity chromatography on IgG-Agarose. The purified proZZ-obelin has both the luminescent activity of obelin and the IgG-binding ability of ZZ-domain. The specific activity of fusion protein was 8.5 x 10(15) photons per mg of protein.

Аннотация: Active hydromedusan and ctenophore Ca2+-regulated photoproteins form complexes consisting of apoprotein and strongly non-covalently bound 2-hydroperoxycoelenterazine (an oxygenated intermediate of coelenterazine). Whereas the absorption maximum of hydromedusan photoproteins is at 460–470 nm, ctenophore photoproteins absorb at 437 nm. Finding out a physical reason for this blue shift is the main objective of this work, and, to achieve it, the whole structure of the protein–substrate complex was optimized using a linear scaling quantum–mechanical method. Electronic excitations pertinent to the spectra of the 2-hydroperoxy adduct of coelenterazine were simulated with time-dependent density functional theory. The dihedral angle of 60° of the 6-(p-hydroxy)-phenyl group relative to the imidazopyrazinone core of 2-hydroperoxycoelenterazine molecule was found to be the key factor determining the absorption of ctenophore photoproteins at 437 nm.

Аннотация: Ca2+-regulated photoproteins of ctenophores lose bioluminescence activity when exposed to visible light. Little is known about the chemical nature of chromophore photo-inactivation. Using a total synthesis strategy, we have established the structures of two unusual coelenterazine products, isolated from recombinant berovin of the ctenophore Beroe abyssicola, which are Z/E isomers. We propose that during light irradiation, these derivatives are formed from 2-hydroperoxycoelenterazine via the intermediate 8a-peroxide by a mechanism reminiscent of that previously described for the auto-oxidation of green-fluorescent-protein-like chromophores.

Аннотация: Upon binding their metal ion cofactors, Ca2+-regulated photoproteins display a rapid increase of light signal, which reaches its peak within milliseconds. In the present study, we investigate bioluminescence kinetics of the entire photoprotein family. All five recombinant hydromedusan Ca2+-regulated photoproteinsaequorin from Aequorea victoria, clytin from Clytia gregaria, mitrocomin from Mitrocoma cellularia and obelins from Obelia longissima and Obelia geniculatademonstrate the same bioluminescent kinetics pattern. Based on these findings, for the first time we propose a unanimous kinetic model describing the bioluminescence mechanism of Ca2+-regulated photoproteins.

To date, three nonallelic isoforms of different lengths (17-24 kDa) for M. longa luciferase have been cloned. All the isoforms are single-chain proteins consisting of a 17-residue signal peptide for secretion, variable N-terminal part and conservative C-terminus responsible for luciferase activity. In contrast to other bioluminescent proteins containing a lot of aromatic residues which are frequently involved in light emission reaction, the C-terminal part of MLuc contains only four Phe, two Tyr, one Trp and two His residues. To figure out whether Tyr residues influence bioluminescence, we constructed the mutants with substitution of Tyr to Phe (Y72F and Y80F). Tyrosine substitutions do not eliminate the ability of luciferase to bioluminescence albeit significantly reduce relative specific activity and change bioluminescence kinetics. In addition, the Tyr replacements have no effect on bioluminescence spectrum, thereby indicating that tyrosines are not involved in the emitter formation. However, as it was found that the intrinsic fluorescence caused by Tyr residues is quenched by a reaction substrate, coelenterazine, in concentration-dependent manner, we infer that both tyrosine residues are located in the luciferase substrate-binding cavity.

Аннотация: Luminous organisms use different protein-mediated strategies to modulate light emission color. Here, we report the transient-state kinetic studies of the interaction between photoprotein clytin from Clytia gregaria and its antenna protein, cgreGFP. We propose that cgreGFP forms a transient complex with Ca2+-bound clytin before the excited singlet state of the coelenteramide product is formed. From the spectral distribution and donor-acceptor separation distance, we infer that clytin reaction intermediates may interact only with the middle side part of cgreGFP.

Аннотация: Light-sensitive Ca2+-regulated photoproteins are responsible for the bright bioluminescence of ctenophores. Using functional screening, four full-size cDNA genes encoding the same 208-amino-acid polypeptide were isolated from two independent cDNA libraries prepared from two Beroe abyssicola specimens. Sequence analysis revealed three canonical EF-hand calcium-binding sites characteristic of Ca2+-regulated photoproteins, but a very low degree of sequence identity (2729%) with aequorin-type photoproteins, despite functional similarities. Recombinant berovin was expressed in Escherichia coli cells, purified, converted to active photoprotein and characterized. Active berovin has absorption maxima at 280 and 437 nm. The Ca2+-discharged protein loses visible absorption, but exhibits a new absorption maximum at 335 nm. The berovin bioluminescence is blue (?max = 491 nm) and a change in pH over the range 6.09.5 has no significant effect on the light emission spectrum. By contrast, the fluorescence of Ca2+-discharged protein (?ex = 350 nm) is pH sensitive: at neutral pH the maximum is at 420 nm and at alkaline pH there are two maxima at 410 and 485 nm. Like native ctenophore photoproteins, recombinant berovin is also inactivated by light. The Ca2+ concentrationeffect curve is a sigmoid with a slope on a loglog plot of similar to 2.5. Although this curve for berovin is very similar to those obtained for obelin and aequorin, there are evident distinctions: berovin responds to calcium changes at lower concentrations than jellyfish photoproteins and its Ca2+-independent luminescence is low. Recombinant berovin was successfully expressed in mammalian cells, thereby demonstrating potential for monitoring intracellular calcium.

Bioluminescence -- Photoprotein -- Trp fluorescence
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.
