CC   -!- FUNCTION: Pyridoxal kinase involved in the salvage pathway of pyridoxal
CC       5'-phosphate (PLP). Catalyzes the phosphorylation of pyridoxal to PLP.
CC       {ECO:0000255|HAMAP-Rule:MF_01639}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=pyridoxal + ATP = pyridoxal 5'-phosphate + ADP + H(+);
CC         Xref=Rhea:RHEA:10224, ChEBI:CHEBI:15378, ChEBI:CHEBI:17310,
CC         ChEBI:CHEBI:30616, ChEBI:CHEBI:456216, ChEBI:CHEBI:597326;
CC         EC=2.7.1.35; Evidence={ECO:0000255|HAMAP-Rule:MF_01639};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_01639};
CC   -!- PATHWAY: Cofactor metabolism; pyridoxal 5'-phosphate salvage; pyridoxal
CC       5'-phosphate from pyridoxal: step 1/1. {ECO:0000255|HAMAP-
CC       Rule:MF_01639}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01639}.
CC   -!- SIMILARITY: Belongs to the pyridoxine kinase family. PdxY subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_01639}.
