... paper summarizes evidence for two modes of regulation of activity: first, by redox-induced conformational changes involving the K-proton uptake path; and secondly, by ligand binding to a conserved site immediately adjacent to the entrance of the K-path that leads to the active site. Both these phenomena...

.... In addition, it has been demonstrated that a light-activated conformational change of the protein is necessary to activate catalysis. This makes POR a very important model system to study the relationship between structural changes of enzymes and functionality. 1 To whom correspondence should...

... and comprises an initial photochemical reaction, which is followed by a number of ‘dark’ steps. The latter steps in the reaction cycle have been shown to involve a series of ordered product release and substrate rebinding events and are known to require conformational changes in the protein in order to proceed...

... to this, a conformation-linked mechanism for redox-driven proton translocation is discussed. By means of electron microscopy, we show that both arms of the Escherichia coli complex I are widened after the addition of NADH but not of NADPH. NADH-induced conformational changes were also detected in solution: ATR-FTIR...

Our results suggest that the topological relationship between the central region and the GHKL domain may alter as a consequence of conformational changes induced in response...
