KEGG   ENZYME: 2.7.7.93
Entry
EC 2.7.7.93                 Enzyme                                 

Name
phosphonoformate cytidylyltransferase;
phpF (gene name)
Class
Transferases;
Transferring phosphorus-containing groups;
Nucleotidyltransferases
Sysname
CTP:phosphonoformate cytidylyltransferase
Reaction(IUBMB)
CTP + phosphonoformate = CMP-5'-phosphonoformate + diphosphate [RN:R08867]
Reaction(KEGG)
R08867
Substrate
CTP [CPD:C00063];
phosphonoformate [CPD:C06456]
Product
CMP-5'-phosphonoformate [CPD:C17945];
diphosphate [CPD:C00013]
Comment
The enzyme, characterized from the bacterium Streptomyces viridochromogenes, participates in the biosynthesis of the herbicide antibiotic bialaphos. The enzyme from the bacterium Kitasatospora phosalacinea participates in the biosynthesis of the related compound phosalacine. Both compounds contain the nonproteinogenic amino acid L-phosphinothricin that acts as a potent inhibitor of EC 6.3.1.2, glutamine synthetase.
