ENZYME entry: EC 3.1.3.74

Accepted Name
Pyridoxal phosphatase.
Alternative Name(s)
PLP phosphatase.
PNP phosphatase.
Vitamin B(6) (pyridoxine) phosphatase.
Vitamin B(6)-phosphate phosphatase.
Vitamin B6 (pyridoxine) phosphatase.
Vitamin B6-phosphate phosphatase.
Reaction catalysed
Pyridoxal 5'-phosphate + H(2)O <=> pyridoxal + phosphate
Cofactor(s)
Mg(2+).
Comment(s)
  • Specific for phosphorylated vitamin B(6) 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 and EC 3.1.3.2, but these enzymes have very broad substrate specificities.
