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. | ||||||||

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. | ||||||||

EC | 1.2.1.81 | ||||||||
Accepted name: | sulfoacetaldehyde dehydrogenase (acylating) | ||||||||
Reaction: | 2-sulfoacetaldehyde + CoA + NADP+ = sulfoacetyl-CoA + NADPH + H+ | ||||||||
Glossary: | 2-sulfoacetaldehyde = 2-oxoethanesulfonate | ||||||||
Other name(s): | SauS | ||||||||
Systematic name: | 2-sulfoacetaldehyde:NADP+ oxidoreductase (CoA-acetylating) | ||||||||
Comments: | The enzyme is involved in degradation of sulfoacetate. In this pathway the reaction is catalysed in the reverse direction. The enzyme is specific for sulfoacetaldehyde and NADP+. | ||||||||

EC | 1.4.99.2 | ||||||||
Accepted name: | taurine dehydrogenase | ||||||||
Reaction: | taurine + H2O + acceptor = 2-sulfoacetaldehyde + NH3 + reduced acceptor | ||||||||

Accepted name: | sulfoacetaldehyde acetyltransferase | ||||||||
Reaction: | acetyl phosphate + sulfite = 2-sulfoacetaldehyde + phosphate | ||||||||
Glossary: | 2-sulfoacetaldehyde = 2-oxoethanesulfonate | ||||||||
Other name(s): | Xsc | ||||||||
Systematic name: | acetyl-phosphate:sulfite S-acetyltransferase (acyl-phosphate hydrolysing, 2-oxoethyl-forming) | ||||||||
Comments: | The reaction occurs in the reverse direction to that shown above. Requires Mg2+. | ||||||||

EC | 2.6.1.55 | ||||||||
Accepted name: | taurine—2-oxoglutarate transaminase | ||||||||
Reaction: | taurine + 2-oxoglutarate = 2-sulfoacetaldehyde + L-glutamate | ||||||||
Glossary: | 2-sulfoacetaldehyde = 2-oxoethanesulfonate taurine = 2-aminoethanesulfonate |

Other name(s): | taurine aminotransferase; taurine transaminase; taurine—α-ketoglutarate aminotransferase; taurine—glutamate transaminase | ||||||||
Systematic name: | taurine:2-oxoglutarate aminotransferase | ||||||||
Comments: | A pyridoxal-phosphate protein. Also acts on D,L-3-amino-isobutanoate, β-alanine and 3-aminopropanesulfonate. Involved in the microbial utilization of β-alanine. | ||||||||

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. | ||||||||
