Protein attributes
| Sequence length | 588 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Cell wall formation. Essential for the formation of a septum of the murein sacculus. Synthesis of cross-linked peptidoglycan from the lipid intermediates. |
| Catalytic activity | (GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala))(n)-diphosphoundecaprenol + GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala)-diphosphoundecaprenol = (GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala))(n+1)-diphosphoundecaprenol + undecaprenyl diphosphate. |
| Pathway | |
| Subcellular location | Cell inner membrane; Single-pass membrane protein; Periplasmic side. Note: The bulk of the molecule, except for the N-terminal membrane anchor region, protrudes into the periplasmic space, where it acts on murein. |
| Domain | Has an N-terminal penicillin insensitive transglycosylase domain (formation of linear glycan strands) and a C-terminal penicillin-sensitive transpeptidase domain (cross-linking of the peptide subunits). |
| Sequence similarities | Belongs to the transpeptidase family. |
