1.3.99.B15 an archaeal alpha-reduced dolichyl phosphate + reduced acceptor although HVO_1799 contributes to dolichol phosphate omega-position isoprene reduction, the absence of HVO_1799 does not prevent N-glycosylation in Haloferax volcanii 430881 1.3.99.B15 an archaeal alpha-reduced dolichyl phosphate + reduced acceptor the enzyme contributes to dolichol phosphate omega-position isoprene reduction. The actual substrate used by this enzyme has not been experimetally determined 430881
