General Information
General Information on EC 1.3.1.94 - polyprenol reductase
Please wait a moment until all data is loaded. This message will disappear when all data is loaded.
physiological function
enzyme is necessary for the reduction of the alpha-isoprene unit of polyprenols to form dolichols, required for synthesis of dolichol-linked monosaccharides and the oligosaccharide precursor used for N-glycosylation
physiological function
Srd5a3 mutation is lethal in mouse and results in an activation of the unfolded protein response pathway
physiological function
-
the activities of yeast cis-prenyltransferases Rer2p and Srt1p and polyprenol reductase are not co-regulated and the reductase may be the rate-limiting enzyme in dolichol synthesis if the amount of polyisoprenoids synthesized exceeds a certain level
