ENZYME entry: EC

Accepted Name
Thiosulfate--dithiol sulfurtransferase.
Alternative Name(s)
Thiosulfate reductase.
Reaction catalysed
Thiosulfate + dithioerythritol <=> sulfite + 4,5-cis-dihydroxy-1,2-dithiacyclohexane + sulfide
  • The enzyme from Chlorella shows very little activity toward monothiols such as glutathione and cysteine (cf. EC
  • The enzyme probably transfers the sulfur atom onto one thiol group to form -S-S(-), and sulfide is spontaneously expelled from this by reaction with the other thiol group.
  • May be identical with EC
