pyridoxal phosphatase EC#: 3.1.3.74; ChemWhat Code: 1379510
| Product Name | pyridoxal phosphatase |
| Example Structure | ![]() |
| Synonyms | PDXP, PLP phosphatase, PLP-P, PLPase, PLPP, PLPP/CIN, PNP phosphatase, pyridoxal phosphatase, pyridoxal phosphate phosphatase, pyridoxal-5′-phosphate phosphatase, pyridoxal-5′-phosphate phosphatase/chronophin, pyridoxal-5?-phosphate (PLP)-phosphatase/chronophin, pyridoxal-specific phosphatase, pyridoxine 5′-phosphate phosphatase, pyridoxine phosphate phosphatase, vitamin B6 (pyridoxine) phosphatase, vitamin B6-phosphate phosphatase, YZGD |
| EC Number | 3.1.3.74 |
| CAS Registry Number | |
| 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. |
| Cofactor | Mg2+ |
| History | |
| Reactions | Pyridoxal 5′-phosphate + H(2)O = pyridoxal + phosphate. |
