<p>GDP-D-mannose is a natural mannosyl donor and substrate for mannosyltransferases that catalyses mannosylation, for instance during the synthesis of the trimannoside core of complex, high-mannose or hybrid N-glycans. GDP-D-mannose is widely used in (chemo)enzymatic synthesis of oligosaccharides and its biosynthesis occurs from glucose-6-phosphate over several steps. GDP-D-mannose consists of a D-mannose unit, α-glycosydically linked to the nucleotide guanosine diphosphate (GDP). Examples of this important reaction would be the transfer of mannosyl moieties onto the dolichol-P-P-GlcNAc2 precursor of N-glycans in the endoplasmatic reticulum, with release of GDP, or the mannosylation reactions during GPI-anchor (bio)synthesis. GDP-D-mannose has also been used for the in vitro synthesis of b-mannan oligosaccharides.</p>
