Subcellular LocationMembrane (Integral component of membrane)
Function in Native Organism 1) Transfer the C.jejuni heptasaccharide to the Acceptor protein AcrA in E.coli.
Additional Information1) 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.
