| Protein names | Recommended name: Penicillin-binding protein 1A Short name=PBP-1a Short name=PBP1a | ||||||
| Gene names |
| ||||||
| Organism | Escherichia coli (strain K12) [Reference proteome] [HAMAP] | ||||||
| Taxonomic identifier | 83333 [NCBI] | ||||||
| Taxonomic lineage | Bacteria › Proteobacteria › Gammaproteobacteria › Enterobacteriales › Enterobacteriaceae › Escherichia › ![]() |
Protein attributes
| Sequence length | 850 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Cell wall formation. Synthesis of cross-linked peptidoglycan from the lipid intermediates. The enzyme has a penicillin-insensitive transglycosylase N-terminal domain (formation of linear glycan strands) and a penicillin-sensitive transpeptidase C-terminal domain (cross-linking of the peptide subunits). |
| Pathway | |
| Subcellular location | Cell inner membrane; Single-pass type II membrane protein By similarity. |
| Sequence similarities | In the N-terminal section; belongs to the glycosyltransferase 51 family. In the C-terminal section; belongs to the transpeptidase family. |
| Sequence caution | The sequence AAA58193.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. |
