Comments [?]

Function Pyridoxal kinase involved in the salvage pathway of pyridoxal 5'-phosphate (PLP). Catalyzes the phosphorylation of pyridoxal to PLP.
Catalytic activity RHEA:10224: ATP + pyridoxal = ADP + H(+) + pyridoxal 5'-phosphate
Cofactor Mg(2+)
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.
