IUBMB Comments

The enzyme from Chlorella shows very little activity towards monothiols such as glutathione and cysteine (cf. EC 2.8.1.3 thiosulfate-thiolsulfurtransferase). 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 2.8.1.1 thiosulfate sulfurtransferase.

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

Synonyms
thiosulfate reductase, thiosulfate-dithiol sulfurtransferase, more
