The Mv1751 gene product is thought to catalyze the first step in the N-glycosylation pathway in Methanococcus voltae. Here, we show that a conditional lethal mutation in the alg7 gene (N-acetylglucosamine-1-phosphate transferase) in Saccharomyces cerevisiae was successfully complemented with Mv1751, highlighting a rare case of cross-domain complementation.
