Hinge-bending motion
Webb31 aug. 2001 · We report a flexible strategy for transducing ligand-binding events into electrochemical responses for a wide variety of proteins. The method exploits ligand-mediated hinge-bending motions, intrinsic to the bacterial periplasmic binding protein superfamily, to establish allosterically controlled interactions between electrode … WebbDorsiflexion and plantar flexion are movements at the ankle joint, which is a hinge joint. Lifting the front of the foot, so that the top of the foot moves toward the anterior leg is …

Webb22 maj 2007 · Motions play an essential role in catalysis and protein-ligand interactions. In particular, hinge bending motions account for 45% of motions in a representative set from the Database of Macromolecular Motions[] comprising domain hinge motions (31% of the total) and fragment hinge motions (14%) [2–4].Thus understanding fundamental … Webb15 nov. 1986 · An axis for the hinge-bending mode is determined by comparing the apo and holo structures; it is shown to yield a sliding displacement of the catalytic domain relative to the coenzyme binding domain, quite different from what would be the least motion path toclosed structure.
Webb21 mars 2024 · A lot of people experience pain when bending forward because that’s the bending motion they make most often. “But your spine isn’t just meant to forward bend. It’s meant to do many other things, like bend sideways and backward,” says Dr. Lu. “Encouraging other positions that bend your spine will always improve your ability to … Webb9 apr. 2024 · Hinge-bending movements in proteins comprising two or more domains form a large class of functional movements. Hinge-bending regions demarcate protein domains and collectively control the domain movement. Consequently, the ability to recognise sequence features of hinge-bending regions and to be able to predict them from …
WebbThe conformational change observed in enzyme-substrate complexes as compared to the unbound enzyme state, and in particular the hinge-bending motions observed in enzymes with two domains, have a substantial effect on the enzymatic catalytic activity. WebbThe largest-amplitude collective motion predicted by this method compares well with the crystallographically observed hinge-bending motion. Such a result supports those obtained previously in the case of hinge-bending motions of smaller systems, such as lysozyme or hexokinase.
WebbAnalysis of the mode shows that the relaxation associated with the hinge bending is highly delocalized; that is, the dihedral angle and energy changes are distributed over many residues, including some (e.g., Trp-28) that are distant from the cleft and hinge region.
