GDP-D-mannose (CAS 3123-67-9)

GDP-D-mannose (Guanosine diphosphate mannose) is a nucleotide sugar that participates in a multitude of vital biological processes, including protein glycosylation, cell signaling, and cell adhesion. Its synthesis occurs through the enzymatic conversion of glucose-1-phosphate and guanosine triphosphate (GTP) by the enzyme GDP-mannose pyrophosphorylase (GMPP). Intriguingly, the significance of guanosine diphosphate mannose lies in its role as a substrate for diverse glycosyltransferases. These enzymes facilitate the transfer of the mannose component to specific acceptor molecules. Consequently, a wide range of glycan structures is synthesized, each possessing critical functions in cell adhesion, signaling, and protein folding. Moreover, guanosine diphosphate mannose exerts additional influence by regulating the activity of numerous enzymes and transcription factors. This regulation occurs through the modulation of their glycosylation status. By impacting the glycosylation of these molecules, guanosine diphosphate mannose dynamically influences their functionality and behavior.
