| FUNCTION | Pyridoxal kinase involved in the salvage pathway of pyridoxal 5'-phosphate (PLP). Catalyzes the phosphorylation of pyridoxal to PLP. |
| CATALYTIC ACTIVITY | Reaction=pyridoxal + ATP = pyridoxal 5'-phosphate + ADP + H(+); Xref=Rhea:RHEA:10224, ChEBI:CHEBI:15378, ChEBI:CHEBI:17310, ChEBI:CHEBI:30616, ChEBI:CHEBI:456216, ChEBI:CHEBI:597326; EC=2.7.1.35; |
| COFACTOR | Name=Mg(2+); Xref=ChEBI:CHEBI:18420; |
| PATHWAY | Cofactor metabolism; pyridoxal 5'-phosphate salvage; pyridoxal 5'-phosphate from pyridoxal: step 1/1. |
| SUBUNIT | Homodimer. |
| SIMILARITY | Belongs to the pyridoxine kinase family. PdxY subfamily. |
