Descripción general

Cytosine 5′-monophosphate N-acetylneuraminic acid (CMP-Neu5Ac) is a sugar-nucleotide produced by CMP-Neu5Ac synthetase from CTP and Neu5Ac.

Aplicación

Cytidine-5′-monophospho-N-acetylneuraminic acid sodium salt has been used:
  • as a standard in high-performance anion-exchange chromatography with pulsed amperometric detection (HPAEC-PAD) for nucleotide sugar analysis in Joubert syndrome type 10 (JBTS10) patient cells and control skin fibroblasts,
  • As a substrate for the enzymatic sialylation of G2 glycoforms, resialylation assay,
  • in in-vitro sialyltransferase assay

Acciones bioquímicas o fisiológicas

Cytidine-5′-monophospho-N-acetylneuraminic acid (CMP-Sialic acid) is a substrate for sialyltransferases. It is used for the enzymatic sialylation of glycans.
Cytosine 5′-monophosphate N-acetylneuraminic acid (CMP-Neu5Ac) is used as a substrate for Golgi sialyltransferases to form sialic acid and its conjugates.

Nota de preparación

Enzymatically prepared by the method of Schauer, R., et al., Hoppe Seyler′s Z. Physiol. Chem., 353, 883 (1972).

Sialyltransferases (STs) represent an important group of enzymes that transfer N-acetylneuraminic acid (Neu5Ac) from cytidine monophosphate-Neu5Ac to various acceptor substrates. In higher animals, sialylated oligosaccharide structures play crucial roles in many biological processes but also in diseases, notably in microbial

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.
