General description

Guanosine 5′-diphospho-D-mannose (GDP-D-mannose) is present in high cytosolic levels in Saccharomyces cerevisiae. It is crucial for protein mannosylation. GDP-D-mannose is an important precursor to produce GDP-l-fucose.

Application

Guanosine 5′-diphospho-D-mannose sodium salt from Saccharomyces cerevisiae has been used as a nucleotide sugar in transglycosylation enzymatic assay and hydrolysis based catalytic reactions with S-glycosyltransferases (SunS).
Guanosine 5′-diphospho-D-mannose sodium salt has been used as a component of ATP regeneration system for in vitro vesicle formation from Saccharomyces cerevisiae microsomes. It has also been used as a component of the buffer for mannosyl transferase activity assay.

Biochem/physiol Actions

Guanosine diphosphate mannose (GDP-mannose) is a nucleotide sugar substrate for glycosyltransferase (mannosylation) reactions mediated by mannosyltransferases.

Glycosyltransferases: Tools for Synthesis and Modification of Glycans

The presence of multiple functional groups and stereocenters in complex carbohydrates makes them challenging targets for the organic chemist.

Glycosyltransferases

Glycosyltransferases were initially considered to be specific for a single glycosyl donor and acceptor, which led to the one enzyme-one linkage concept. Subsequent observations have refuted the theory of absolute enzymatic specificity by describing the transfer of analogs of some nucleoside mono- or diphosphate sugar donors.
