Pyridoxal kinase is an enzyme that in humans is encoded by the PDXK gene.The protein encoded by this gene phosphorylates vitamin B6 a step required for the conversion of vitamin B6 to pyridoxal-5-phosphate an important cofactor in intermediary metabolism. The encoded protein is cytoplasmic and probably acts as a homodimer. Alternatively spliced transcript variants have been described but their biological validity has not been determined.
