Dolichol-phosphate mannose
WebAbstract. Dolichol phosphate-mannose synthase (Dol-P-Man synthase), which generates dolichol phosphate-mannose (Dol-P-Man) from GDP-mannose (GDP-Man) and dolichol phosphate (Dol-P), is an essential enzyme for all eukaryotic cells. The Dol- P-Man synthase is located in the endoplasmic reticulum (ER), through two kinds of binding to the … WebJul 1, 2008 · The dolichol-phosphate-mannose synthase (DPMS) is a type-II complex composed of three subunits which are DPM1, DPM2 and DPM3 456, 457 .

WebJan 13, 2006 · Dolichol-phosphate mannose (DPM) synthase is required for synthesis of the glycosylphosphatidylinositol (GPI) anchor, N-glycan precursor, protein O-mannose, and C-mannose. We previously identified DPM3, the third component of this enzyme, which was co-purified with DPM1 and DPM2. Dolichols play a role in the co-translational modification of proteins known as N-glycosylation in the form of dolichol phosphate. Dolichols function as a membrane anchor for the formation of the oligosaccharide Glc3-Man9-GlcNAc2 (where Glc is glucose, Man is mannose, and GlcNAc is N … See more Dolichol refers to any of a group of long-chain mostly unsaturated organic compounds that are made up of varying numbers of isoprene units terminating in an α-saturated isoprenoid group, containing an See more Dolichol has been suggested to be used as a biomarker for aging. During aging, the human brain shows a progressive increase in levels of dolichol, a reduction in levels of ubiquinone, but relatively unchanged concentrations of cholesterol and dolichyl phosphate.
