Aquacobalamin reductase (EC 1.16.1.3) is an enzyme that catalyzes the chemical reaction2 cob(II)alamin + NAD+ 2 aquacob(III)alamin + NADH + H+Thus the two substrates of this enzyme are cob(II)alamin and nicotinamide adenine dinucleotide ion whereas its 3 products are aquacob(III)alamin nicotinamide adenine dinucleotide and hydrogen ion.This enzyme belongs to the family of oxidoreductases specifically those oxidizing metal ion with NAD+ or NADP+ as acceptor.
