Pyridoxal 5'-phosphate

Pyridoxal 5'-phosphate is the monophosphate ester obtained by condensation of phosphoric acid with the primary hydroxy group of pyridoxal. It has a role as an EC 2.7.7.7 (DNA-directed DNA polymerase) inhibitor, a coenzyme, a cofactor, a mouse metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a human metabolite. It is a member of methylpyridines, a vitamin B6 phosphate, a monohydroxypyridine and a pyridinecarbaldehyde. It is functionally related to a pyridoxal. It is a conjugate acid of a pyridoxal 5'-phosphate(2-). — ChEBI
