'''PENICILLIN-BINDING PROTEIN 2X (PBP-2X)'''
===PENICILLIN-BINDING PROTEIN 2X (PBP-2X)===




==Overview==
<!--
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.
The line below this paragraph, {{ABSTRACT_PUBMED_8605631}}, adds the Publication Abstract to the page
(as it appears on PubMed at http://www.pubmed.gov), where 8605631 is the PubMed ID number.
