EC | 1.1.1.313 | ||||||||
Accepted name: | sulfoacetaldehyde reductase (NADPH) | ||||||||
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. cf. EC 1.1.1.433, sulfoacetaldehyde reductase (NADH). | ||||||||

Systematic name: | isethionate:NAD+ oxidoreductase | ||||||||
Comments: | The enzymes from the bacteria Bilophila wadsworthia and Clostridium sp. MSTE9 catalyse the reaction only in the reduction direction. In the bacterium Bifidobacterium kashiwanohense the optimal reaction pH for sulfoacetaldehyde reduction is 7.5, while that for isethionate oxidation is 10.0. cf. EC 1.1.1.313, sulfoacetaldehyde reductase (NADPH). | ||||||||

EC | 1.2.1.73 | ||||||||
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. | ||||||||

Glossary: | taurine = 2-aminoethanesulfonate hypotaurine = 2-aminoethanesulfinate 2-sulfoacetaldehyde = 2-oxoethanesulfonate 2-sulfinoacetaldehyde = 2-oxoethanesulfinate |
||||||||
Other name(s): | Tpa | ||||||||
Systematic name: | taurine:pyruvate aminotransferase | ||||||||
Comments: | The enzyme from the bacterium Bilophila wadsworthia requires pyridoxal 5′-phosphate as a cofactor, and catalyses a reversible reaction that starts an anaerobic taurine degradation pathway. β-Alanine is also a significant amino group donor. The enzyme from the bacterium Pseudomonas denitrificans PD1222 can also use hypotaurine, producing 2-sulfinoacetaldehyde, which spontaneously hydrolyses to sulfite and acetaldehyde. Unlike, EC 2.6.1.55, taurine—2-oxoglutarate transaminase, 2-oxoglutarate cannot serve as an acceptor for the amino group. | ||||||||
