Induced-fit mechanism
Web30 mei 2014 · We could identify an induced-fit mechanism by elucidating a rearrangement of the G1/2 helix-break motif upon substrate binding. This rearrangement highlights a novel effector triad comprising the pyrophosphate sensor Arg178, the linker Asp181, and the effector Gly182-O.

Web18 sep. 2024 · SBPs bind their cognate ligand(s) via an induced-fit mechanism known as the "Venus Fly-trap"; however, this mechanism lacks the atomic details of all conformational landscape as the confirmatory evidence(s) in its support. In this study, we delineate the atomic details of an SBP, β-glucosides-binding protein (βGlyBP) from Thermus … WebInduced fit. The matching between an enzyme's active site and the substrate isn’t just like two puzzle pieces fitting together (though scientists once thought it was, in an old model called the “lock-and-key” model). Instead, an enzyme changes shape slightly when it binds its substrate, resulting in an even tighter fit.
Web22 sep. 2024 · The induced-fit model is generally considered the more correct version. This theory maintains that the active site and the substrate are, initially, not perfect matches for each other. Rather,...
