Although the structure of bacterial N-glycan is different from that observed in eukaryotes, engineering of Campylobacter N-linked glycosylation pathway into E. coli, provides an opportunity to express heterologous proteins in glycosylated form in E. coli.
Expression of Pglb
oligosaccharyltransferase or (OTase) from C. jejuni in
E. coli showed a significant increase in glycopepetide
yield [42,43]. Recently efforts has been made to produce
glycosylated proteins with substrates other than native and
non-native to E. coli and C.jejuni [44-48].
