Sulfoacetaldehyde dehydrogenase

Sulfoacetaldehyde dehydrogenase (EC 1.2.1.73, SafD) is an enzyme with systematic name 2-sulfoacetaldehyde:NAD⁺ oxidoreductase.^[1] This enzyme catalyses the following chemical reaction

2-sulfoacetaldehyde + H₂O + NAD⁺

\rightleftharpoons

sulfoacetate + NADH + 2 H⁺

This reaction is part of a bacterial pathway that can make use the amino group of taurine as a sole source of nitrogen for growth.
