Common Name

Pyridoxine

Description

Pyridoxine, also known as pyridoxol or vitamin B6, belongs to the class of organic compounds known as pyridoxines. These are pyridoxal derivatives in which the carbaldehyde group at position 2 of the pyridoxal moiety is replaced by a hydroxymethyl group. Pyridoxine exists as a solid, possibly soluble (in water), and a very strong basic compound (based on its pKa) molecule. Pyridoxine exists in all living species, ranging from bacteria to humans. Pyridoxine participates in a number of enzymatic reactions, within cattle. In particular, Pyridoxine can be converted into pyridoxal; which is catalyzed by the enzyme pyridoxine-5'-phosphate oxidase. In addition, Pyridoxine can be converted into pyridoxine 5'-phosphate; which is catalyzed by the enzyme pyridoxal kinase. In cattle, pyridoxine is involved in the metabolic pathway called the vitamin B6 metabolism pathway. Pyridoxine is a potentially toxic compound.

2. Pyridoxal phosphate phosphatase

General function:: Carbohydrate transport and metabolism
Specific function:: Protein serine phosphatase that dephosphorylates 'Ser-3' in cofilin and probably also dephosphorylates phospho-serine residues in DSTN.
