IUBMB Comments

Requires Mg2+. This enzyme is specific for phosphorylated vitamin B6 compounds: it acts not only on pyridoxal phosphate (PLP), but also on pyridoxine phosphate (PNP), pyridoxamine phosphate (PMP), 4-pyridoxic acid phosphate and 4-deoxypyridoxine phosphate. This reaction can also be carried out by EC 3.1.3.1 (alkaline phosphatase) and EC 3.1.3.2 (acid phosphatase), but these enzymes have very broad substrate specificities.

The expected taxonomic range for this enzyme is: Bacteria, Eukaryota, Archaea

Synonyms
plpp/cin, plp phosphatase, pyridoxal phosphatase, pyridoxal phosphate phosphatase, pyridoxine phosphate phosphatase, plpase, pyridoxal-5'-phosphate phosphatase, pyridoxal-5'-phosphate phosphatase/chronophin, pnp phosphatase, pyridoxine 5'-phosphate phosphatase, more
