General annotation (Comments)

Function	Catalyzes the sequential NAD-dependent oxidations of L-histidinol to L-histidinaldehyde and then to L-histidine By similarity.
Catalytic activity	L-histidinol + 2 NAD+ = L-histidine + 2 NADH. HAMAP MF_01024
Cofactor	Binds 1 zinc ion per subunit By similarity.
Pathway	Amino-acid biosynthesis; L-histidine biosynthesis; L-histidine from 5-phospho-alpha-D-ribose 1-diphosphate: step 9/9. HAMAP MF_01024
Subunit structure	Homodimer By similarity.
Sequence similarities	Belongs to the histidinol dehydrogenase family.
