Aminobutyraldehyde dehydrogenase belongs to the family of oxidoreductases (an enzyme that catalyzes the transfer of electrons from one molecule, the reductant to the oxidant), with the systematic name of 4-aminobutanal:NAD+ 1-oxidoreductase.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with NAD+ or NADP+ as acceptor. In biochemistry, an oxidoreductase is an enzyme that catalyzes the transfer of electrons from one molecule, the reductant, also called the electron donor, to another, the oxidant, also called the electron acceptor. The systematic name of this enzyme class is 4-aminobutanal:NAD+ 1-oxidoreductase.
