Protein allostery
Webballostery: , allostery ( ă-los'ter-izm, -los'ter-ē ), The influencing of an enzyme activity, or the binding of a ligand to a protein, by a change in the conformation of the protein, brought about by the binding of a substrate or other effector at a site (allosteric site) other than the active site of the protein. Compare: cooperativity , ... WebbHere, we trace the evolution of two allosteric activator motifs within the yeast scaffold protein Ste5 that specifically target the mating MAP kinase Fus3. One activator (Ste5-VWA) provides pathway insulation and dates to the divergence of Fus3 from its paralog, Kss1; a second activator (Ste5-FBD) that tunes mating behavior is, in contrast, not ...

Webb10 mars 2024 · Proteins have an active site (pink) and allosteric sites (yellow). In a cell, a protein’s partner makes a modification (top, center) that then interacts with an allosteric site (bottom, center) to control the protein’s activity. HotSpot Therapeutics is designing small molecules that mimic that interaction (bottom, right). Locksmiths abound Webb) • Hot Spots – Individual residues within the binding interface that greatly effect overall binding affinity (ΔGbind) Interaction Surfaces Allostery & Cooperativity • Allostery – An allosteric protein’s activity can be modulated by interactions at “another” site away from the “active” site First event helps the second event occur, leading to ultrasensitivity ...
WebbDynamic allostery is predicted based on a quasi-harmonic normal mode analysis using a perturbation scan. An allosteric mechanism known to inhibit enzymatic function in TEM beta-lactamase is identified, ... is distal from the active site and stabilizes the protein against structural changes.

WebbThe novel framework is applied to three membrane proteins: a voltage-gated ion channel (KCNQ1), a G-protein coupled receptor (GPCR - β2 adrenergic receptor), and a pH-gated ion channel (KcsA). Through systematic analysis of the obtained networks and their components, we demonstrate the importance of lipids for membrane protein allostery.
