Thiosulfate is able to transfer its sulfur atom to glutathione, a reaction investigated in yeast (Chauncey & Westley 1983). Recombinant human thiosulfate sulfurtransferase/rhodanese-like domain-containing protein 1 (TSTD1 aka KAT1) (and its yeast equivalent RDL1) catalyse a predicted thiosulfate-dependent conversion of glutathione (GSH) to glutathione disulfide (GSSG) (Melideo et al. 2014).
