This domain is found at the N terminus of Class B High Molecular Weight Penicillin-Binding Proteins. Its function has not been precisely defined, but is strongly implicated in PBP polymerisation. The domain forms a largely disordered 'sugar tongs' structure.	Domain
A, B, C	PF00905	Penicillin binding protein transpeptidase domain (Transpeptidase)	Penicillin binding protein transpeptidase domain	The active site serine (residue 337 in Swiss:P14677) is conserved in all members of this family.	Domain
A, B, C	PF05223	NTF2-like N-terminal transpeptidase domain (MecA_N)	NTF2-like N-terminal transpeptidase domain	The structure of this domain from MecA is known [1] Swiss:Q53707 and is found to be similar to that found in NTF2 Pfam:PF02136. This domain seems unlikely to have an enzymatic function, and its role remains unknown.	Domain
