EC 1.2.1.73 Details
EC number
1.2.1.73
Accepted name
sulfoacetaldehyde dehydrogenase
Reaction
2-sulfoacetaldehyde + H2O + NAD+ = sulfoacetate + NADH + 2 H+
Other name(s)
SafD
Systematic name
2-sulfoacetaldehyde:NAD+ oxidoreductase
Comment
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.
