Accepted name: sulfoacetaldehyde dehydrogenase
Reaction: 2-sulfoacetaldehyde + H2O + NAD+ = sulfoacetate + NADH + 2 H+
Glossary: 2-sulfoacetaldehyde = 2-oxoethanesulfonate
taurine = 2-aminoethanesulfonate
Other name(s): SafD
Systematic name: 2-sulfoacetaldehyde:NAD+ oxidoreductase
Comments: This reaction is part of a bacterial pathway that can utilize the amino group of taurine as a sole source of nitrogen for growth. At physiological concentrations, NAD+ cannot be replaced by NADP+. The enzyme is specific for sulfoacetaldehyde, as formaldehyde, acetaldehyde, betaine aldehyde, propanal, glyceraldehyde, phosphonoacetaldehyde, glyoxylate, glycolaldehyde and 2-oxobutyrate are not substrates.
