Protein
Protein glycosylation K
Organism
Campylobacter jejuni subsp. jejuni serotype O:2 (strain ATCC 700819 / NCTC 11168)
Function
Mediates the ATP-dependent translocation of the undecaprenylpyrophosphate-linked heptasaccharide intermediate across the cell membrane; this is an essential step during the N-linked protein glycosylation pathway. Transport across the membrane is effected via ATP-driven conformation changes. Most likely, only the polar and charged part of the glycolipid enter the substrate-binding cavity, and the lipid tail remains exposed to the membrane lipids during the transmembrane flipping process.
Similarity
Belongs to the ABC transporter superfamily.
