Entry
EC 1.1.1.313                Enzyme                                 
Name
sulfoacetaldehyde reductase;
isfD (gene name)
Class

Acting on the CH-OH group of donors;
With NAD+ or NADP+ as acceptor
BRITE hierarchy
Sysname
isethionate:NADP+ oxidoreductase
Reaction(IUBMB)
isethionate + NADP+ = 2-sulfoacetaldehyde + NADPH + H+ [RN:R02600]
Reaction(KEGG)
Substrate
isethionate [CPD:C05123];
NADP+ [CPD:C00006]
Product
2-sulfoacetaldehyde [CPD:C00593];
NADPH [CPD:C00005];
H+ [CPD:C00080]
Comment
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.
