Аннотация: Many proteins require a non-covalently bound ligand to be functional. How ligand binding affects protein conformation is often unknown. Here we address thermal unfolding of the free and ligand-bound forms of photoprotein obelin. Fluorescence and far-UV circular dichroism ( CD) data show that the various ligand-dependent conformational states of obelin differ significantly in stability against thermal unfolding. Binding of coelenterazine and calcium considerably stabilizes obelin. In solution, all obelin structures are similar, except for apo-obelin without calcium. This latter protein is an ensemble of conformational states, the populations of which alter upon increasing temperature. (C) 2012 Federation of European Biochemical Societies.

Ключевые слова (''Своб.индексиров.''): bioluminescence--ef-hand--coelenteramider--luciferase--ca2+-binding protein
Аннотация: The crystal structure of the Ca2+-loaded coelenterazine binding protein from Renilla muelleri in its apo-state has been determined at resolution 1.8 angstrom. Although calcium binding hardly affects the compact scaffold and overall fold of the structure before calcium addition, there are easily discerned shifts in the residues that were interacting with the coelenterazine and a repositioning of helices, to expose a cavity to the external solvent. Altogether these changes offer a straightforward explanation for how following the addition of Ca2+, the coelenterazine could escape and become available for bioluminescence on Renilla luciferase. A docking computation supports the possibility of a luciferase-binding protein complex.
