Hypotaurine dehydrogenase belongs to the family of oxidoreductases  (an enzyme that catalyzes the transfer of electrons )and is a hypotaurine, it also has two cofactors.
This enzyme belongs to the family of oxidoreductases, specifically those acting on a sulfur group of donors 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. It has 2 cofactors: heme, and Molybdenum. The systematic name of this enzyme class is hypotaurine:NAD+ oxidoreductase.
