ID 2.5.1.143 DE pyridinium-3,5-biscarboxylic acid mononucleotide synthase. AN NaAD carboxylase/hydrolase. AN nicotinic acid adenine dinucleotide carboxylase/hydrolase. AN P2CMN synthase. CA deamido-NAD(+) + hydrogencarbonate = AMP + 2 H(+) + pyridinium-3,5- CA dicarboxylate mononucleotide. CC -!- This enzyme, found in the bacterium Lactobacillus plantarum, CC is involved in the biosynthesis of a nickel-pincer cofactor. CC -!- It carboxylates the pyridinium ring of deamido-NAD(+) and cleaves the CC phosphoanhydride bond to release AMP and generate pyridinium-3,5- CC biscarboxylic acid mononucleotide (P2CMN).
