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 a coenzyme, a human metabolite, an Escherichia coli metabolite, a Saccharomyces cerevisiae metabolite, a mouse metabolite, an EC 2.7.7.7 (DNA-directed DNA polymerase) inhibitor and a cofactor.

Pyridoxal phosphate (PLP, pyridoxal 5'- phosphate, P5P), the active form of vitamin B 6, is a coenzyme in a variety of enzymatic reactions. The International Union of Biochemistry and Molecular Biology has catalogued more than 140 PLP-dependent activities, corresponding to ~4% of all classified activities. [5] .

磷酸吡哆醛（PLP，维生素B6的主要代谢活性形式）是一种多功能辅酶，参与氨基化合物的代谢，以它为辅酶因子的酶被称作PLP依赖性酶（PLP-dependent enzymes, PLP-DEs），它们在糖，脂和氨基酸等代谢过程中起着重要的作用。

磷酸吡哆醛是一种有机化合物，分子式C8H10NO6P，由维生素B6与磷酸结合形成，包括吡哆醛、吡哆胺、吡哆醇，在体内以磷酸酯的形式存在。 其中磷酸吡哆醛和磷酸吡哆胺可以互相转变，皆为活性型。

PLP-dependent enzymes can catalyze a variety of chemical reactions, such as racemization, decarboxylation, β-addition, β-elimination, retro-aldol cleavage, transamination, and α-elimination. They are biologically synthesized a powerful tool for a variety of natural amino acids, non-natural amino acids and their related compounds.

The B6 coenzymes, composed of pyridoxal 5'-phosphate (PLP) and pyridoxamine 5'-phosphate (PMP), are used by many transaminases, racemases, decarboxylases, and enzymes catalyzing alpha,beta and beta,gamma-eliminations.

Pyridoxal-5'-phosphate (PLP) is an obligatory cofactor for the homodimeric mitochondrial enzyme 5-aminolevulinate synthase (ALAS), which controls metabolic flux into the porphyrin biosynthetic pathway in animals, fungi, and the α-subclass of proteobacteria.
