Beta-lactams inactivate the PBPs by acylating an essential serine residue in the active site of these proteins. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMed All beta-lactam antibiotics exert their biological effects by interacting with a unique class of proteins, the penicillin-binding proteins (PBPs). These membrane proteins are involved in the biosynthesis of the murein or peptidoglycan, a mesh-like structure which completely surrounds the bacterial cell. Sequence similarities indicate that one domain of these proteins belongs to a large family of beta-lactam-recognizing proteins, which includes the active-site serine beta-lactamases. We here report the first three-dimensional crystal structure of a high molecular weight penicillin-binding protein, PBP2x of Streptococcus pneumoniae, at 3.5 A resolution. The molecule has three domains, the central domain being a transpeptidase, which is a suitable target for antibiotic development.
