Deoxyxylulose 5-phosphate
Animals are auxotroph for this enzyme co-factor and require it or an intermediate to be supplemented, hence its classification as a vitamin B6, unlike MoCo or CoQ10 for example. PLP is synthesized from pyridoxal by the enzyme pyridoxal kinase, requiring one ATP molecule. PLP is metabolized in the liver. Two natural pathways for PLP are currently known: one requires deoxyxylulos…
