ID 1.1.1.313 DE sulfoacetaldehyde reductase (NADPH). CA 2-hydroxyethane-1-sulfonate + NADP(+) = H(+) + NADPH + sulfoacetaldehyde. CC -!- Catalyzes the reaction only in the opposite direction. CC -!- Involved in taurine degradation. CC -!- The bacterium Chromohalobacter salexigens strain DSM 3043 possesses CC two enzymes that catalyze this reaction, a constitutive enzyme CC (encoded by isfD2) and an inducible enzyme (encoded by isfD). CC -!- The latter is induced by taurine, and is responsible for most of the CC activity observed in taurine-grown cells. cf. EC 1.1.1.433.
