2.5.1.143 |
Accepted name: |
pyridinium-3,5-biscarboxylic acid mononucleotide synthase |
Reaction: |
deamido-NAD+ + hydrogencarbonate = AMP + pyridinium-3,5-biscarboxylate mononucleotide |
Other name(s): |
LarB; P2CMN synthase; nicotinic acid adenine dinucleotide carboxylase/hydrolase; NaAD carboxylase/hydrolase |
Systematic name: |
deamido-NAD+:hydrogencarbonate nicotinate-β-D-ribonucleotidyltransferase |
Comments: |
This enzyme, found in the bacterium Lactobacillus plantarum, is involved in the biosynthesis of a nickel-pincer cofactor. It carboxylates the pyridinium ring of deamido-NAD+ and cleaves the phosphoanhydride bond to release AMP and generate pyridinium-3,5-biscarboxylic acid mononucleotide (P2CMN). |
