General description

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

Application

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

Biochem/physiol Actions

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.

Preparation Note

Enzymatically prepared by the method of Schauer, R., et al., Hoppe Seyler′s Z. Physiol. Chem., 353, 883 (1972).
CMP-NAN is very acid-labile.

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

Glycosylation of the immunoglobulin G (IgG)-Fc tail is required for binding to Fc-gamma receptors (FcγRs) and complement-component C1q. A variety of IgG1-glycoforms is detected in human sera. Several groups have found global or antigen-specific skewing of IgG glycosylation, for example
