bifunctional glycosyl transferase/transpeptidase; Reviewed

penicillin-binding protein 1B. Bacterial that synthesize a cell wall of peptidoglycan (murein) generally have several transglycosylases and transpeptidases for the task. This family consists of a particular bifunctional transglycosylase/transpeptidase in E. coli and other Proteobacteria, designated penicillin-binding protein 1B.

penicillin-binding protein 1b; Provisional

Bifunctional transglycosylase second domain. UB2H is the second domain of the transglycosylases, or penicillin-binding proteins PBP1bs)), the multi-domain membrane proteins essential for cell wall synthesis that are targeted by penicillin antibiotics. The exact function of the UB2H domain is uncertain, but it may act as the binding component of PBP1b with different binding partners, or it may participate in the regulation between DNA repair and/or synthesis and cell wall formation during the bacterial cell cycle.
