Description
Cytidine 5'-monophosphate, also known as 5'-CMP, is a nucleotide that is used as a monomer in RNA. 5'-CMP is a key intermediate in the preparation of several nucleotide derivatives and is widely used in food and pharmaceutical industries.
Chemical Properties
white crystalline powder
Uses
Cytidine 5′-monophosphate has been used in Raman spectroscopy studies.
Uses
A constituent of nucleic acids. It was isolated from yeast nucleic acid.
Production Methods
As a key intermediate in preparing several nucleotide derivatives, cytidine 5′-monophosphate (5′-CMP) is widely applied in food and pharmaceutical industries. Enzymatic synthesis of 5′-CMP is catalyzed by cytidine kinase (CK, EC 2.7.1.213), a type of nucleoside kinase that belongs to the PfkB family. Li et al. constructed a highly efficient biosynthesis system for manufacturing 5′-CMP in vitro. CK was used for the biotransformation of cytidine to 5′-CMP, while polyphosphate kinase (PPK) was coupled for adenosine triphosphate regeneration. Both CK and PPK were selected from extremophiles, possessing great potential for biocatalytic synthesis. After optimization, 96 mM 5′-CMP was produced within 6 h, and the yield reached nearly 100%[1].
Definition
ChEBI: A pyrimidine ribonucleoside 5'-monophosphate having cytosine as the nucleobase.
Biochem/physiol Actions
Cytidine 5′-monophosphate (CMP) is used as a substrate of uridine monophosphate (UMP)/cytidine monophosphate (CMP) kinase (EC 2.7.4.4) to form CDP which upon phosphorylation to CTP supports DNA and RNA biosynthesis.
