| PF00912 | Transglycosylase (Transgly) | Transglycosylase | The penicillin-binding proteins are bifunctional proteins consisting of transglycosylase and transpeptidase in the N- and C-terminus respectively [1]. The transglycosylase domain catalyses the polymerisation of murein glycan chains ([4]). | Domain | |
| 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 | |
