DescriptionPyridoxine 5'-phosphate, also known as pyridoxine-5P or pyridoxine phosphoric acid, belongs to the class of organic compounds known as pyridoxine-5'-phosphates. These are pyridoxines that carry a phosphate group at the 5-position. Pyridoxine 5'-phosphate is a very strong basic compound (based on its pKa). Pyridoxine 5'-phosphate exists in all living species, ranging from bacteria to humans. Within yeast, pyridoxine 5'-phosphate participates in a number of enzymatic reactions. In particular, pyridoxine 5'-phosphate can be biosynthesized from 1-deoxy-D-xylulose 5-phosphate and 2-amino-3-phosphonopropionic acid; which is catalyzed by the enzyme pyridoxine 5'-phosphate synthase. In addition, pyridoxine 5'-phosphate can be biosynthesized from pyridoxine; which is mediated by the enzyme pyridoxal kinase. In yeast, pyridoxine 5'-phosphate is involved in the metabolic pathway called the vitamin B6 pathway.
