General annotation (Comments)

Function	Catalyzes the reduction of pyridoxal (PL) with NADPH and oxidation of pyridoxine (PN) with NADP+.
Catalytic activity	Pyridoxine + NADP+ = pyridoxal + NADPH. Ref.3 Ref.4
Pathway	Cofactor degradation; B6 vitamer degradation; pyridoxal from pyridoxine (dehydrogenase route): step 1/1.
Subunit structure	Monomer. Ref.3 Ref.4
Subcellular location	Cytoplasm By similarity.
Post-translational modification	The N-terminus is blocked. Ref.3
Sequence similarities	Belongs to the aldo/keto reductase family.
Biophysicochemical properties	Kinetic parameters: KM=0.9 mM for pyridoxal Ref.3 Ref.4 pH dependence: Optimum pH is 6.5-7.5 for the reverse reaction. Ref.3 Ref.4
