Chains Pfam Accession Pfam Identifier Pfam Description Type Source
A PF00905 Transpeptidase Penicillin binding protein transpeptidase domain Domain The active site serine (residue 337 in Swiss:P14677) is conserved in all members of this family. PFAM PF00905
A PF03793 PASTA PASTA domain Domain This domain is found at the C termini of several Penicillin-binding proteins and bacterial serine/threonine kinases [1]. It binds the beta-lactam stem, which implicates it in sensing D-alanyl-D-alanine - the PBP transpeptidase substrate. It is a small globular fold consisting of 3 beta-sheets and an alpha-helix. The name PASTA is derived from PBP and Serine/Threonine kinase Associated domain. PFAM PF03793
A PF03717 PBP_dimer Penicillin-binding Protein dimerisation domain Domain 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. PFAM PF03717
