IUBMB Enzyme Nomenclature

EC 1.1.1.313

Accepted name: sulfoacetaldehyde reductase

Reaction: isethionate + NADP+ = 2-sulfoacetaldehyde + NADPH + H+

Glossary: isethionate = 2-hydroxyethanesulfonate
2-sulfoacetaldehyde = 2-oxoethanesulfonate

Other name(s): isfD (gene name)

Systematic name: isethionate:NADP+ oxidoreductase

Comments: Catalyses the reaction only in the opposite direction. Involved in taurine degradation. The bacterium Chromohalobacter salexigens strain DSM 3043 possesses two enzymes that catalyse this reaction, a constitutive enzyme (encoded by isfD2) and an inducible enzyme (encoded by isfD). The latter is induced by taurine, and is responsible for most of the activity observed in taurine-grown cells.
