Intrinsic enzymatic activities

WebEnzyme-coupled Receptor. Enzyme-coupled receptors are a major kind of cell membrane receptors characterized either by having an intrinsic enzymatic activity on their cytosolic domain or by being coupled with an enzyme. They have two main domains: ligand binding site on the outside and an enzyme binding (catalytic) domain on the inside of the cell. WebA common observation is that intrinsic resistance is associated with a decrease in binding affinity of cephalosporins for the enterococcal PBPs, specifically Pbp5 [28,29]. As a class B PBP possessing only transpeptidase enzymatic activity, Pbp5 must partner with a glycosyltransferase to synthesize peptidoglycan.
