| EMBL CDS | ABB40492.1 |
| Sequence length | 722 AA |
| Subcellular Location | Membrane (Integral component of membrane) |
| Function in Native Organism | 1) Transfer the C.jejuni heptasaccharide to the Acceptor protein AcrA in E.coli. |
| Additional Information | 1) DdPglB does not follow -2 rule, negatively charged residue at the ?2 position of the glycosylation sequon N-X-S/T. 2) PglBDd has relaxed glycan specificity. It can transfer monosaccharide and polysaccharide to AcrA in Escherichia coli apart from C. jejuni heptasaccharide. |

| EC Number (BRENDA) | 2.4.99.19. 13108 |
| Mechanism of Glycan Transfer | En bloc |
| Acceptor specificity Sequon_1 | Asn-Xaa-Ser |
| Donor Type | UndPP-Heptasaccharide |
