CONFORMER SELECTION BY LIGAND BINDING OBSERVED WITH PROTEIN CRYSTALLOGRAPHYCONFORMER SELECTION BY LIGAND BINDING OBSERVED WITH PROTEIN CRYSTALLOGRAPHY
Structural highlights
Function[CCPR_YEAST] Destroys radicals which are normally produced within the cells and which are toxic to biological systems. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedA large-scale movement between "closed" and "open" conformations of a protein loop was observed directly with protein crystallography by trapping individual conformers through binding of an exogenous ligand and characterization with solution kinetics. The buried indole ring of Trp191 in cytochrome c peroxidase (CCP) was displaced by exogenous ligands, causing a conformational change of loop Pro190-Asn195 and exposing Trp191 to the protein surface. Kinetic measurements are consistent with a two-step binding mechanism in which the rate-limiting step is a transition of the protein to the open state, which then binds the ligand. This large-scale conformational change of a functionally important region of CCP is independent of ligand and indicates that about 4% of the wild-type protein is in the open form in solution at any given time.
