allostery in British English (əˈlɒstərɪ) nounthe condition of a protein (such as an enzyme) in which the structure and activity of the enzyme are modified by the binding of a metabolic molecule at a site other than the chemically active one Examples of 'allostery' in a sentenceallostery Using a network-based formalism of allostery, we introduced a community-hopping model of allosteric communication.Here, we provide an introduction to the investigation of protein allostery using molecular dynamics simulation.Here, we review fundamental principles of photoreceptors and light-regulated allostery.Many fundamental cellular processes such as gene expression are tightly regulated by protein allostery.Our study therefore reveals significant features of the mechanistic basis for allostery.The latter we demonstrate as a new exemplar for allostery without conformation change.Regions distal to orthosteric sites indicate long range conformational changes with implications for allostery.Conformational changes drive protein function, including catalysis, allostery and signaling.The concept of allostery has evolved in the past century.Comparison with other related enzymes shows that similar conformational variability and, byimplication, allostery also exist in other papain-like endopeptidases. |
