N-glycosylation in Sulfolobus acidocaldarius

February 20, 2016

Almost all extracellular proteins of archaea are modified by either N- or O-glycosylation or both. We have set out to analyze the N-glycosylation pathway in S. acidocaldarius and used the S-layer protein as a substrate protein. We identified a number of enzymes that play an important role in the N-glycosylation pathway in S. acidocaldarius.
