IUBMB Comments

Catalyses the NADPH-dependent reduction of succinyl-CoA to succinate semialdehyde. The enzyme has been described in Clostridium kluyveri, where it participates in succinate fermentation , and in Metallosphaera sedula, where it participates in the 3-hydroxypropanonate/4-hydroxybutanoate cycle, an autotrophic CO2 fixation pathway found in some thermoacidophilic archaea [2,3].

The expected taxonomic range for this enzyme is: Bacteria, Archaea, Eukaryota

Synonyms
Tneu_0421, more
