penicillin-binding protein, 1A family. Bacterial that synthesize a cell wall of peptidoglycan (murein) generally have several transglycosylases and transpeptidases for the task. This family consists of bifunctional transglycosylase/transpeptidase penicillin-binding proteins (PBP). In the Proteobacteria, this family includes PBP 1A but not the paralogous PBP 1B (TIGR02071). This family also includes related proteins, often designated PBP 1A, from other bacterial lineages. [Cell envelope, Biosynthesis and degradation of murein sacculus and peptidoglycan]

Membrane carboxypeptidase/penicillin-binding protein PbpC [Cell wall/membrane/envelope biogenesis].

Transglycosylase. The penicillin-binding proteins are bifunctional proteins consisting of transglycosylase and transpeptidase in the N- and C-terminus respectively. The transglycosylase domain catalyzes the polymerization of murein glycan chains.
