DE   L-cysteine S-thiosulfotransferase.
CA   (1) 2 Fe(III)-[cytochrome c] + L-cysteinyl-[SoxY protein] + thiosulfate =
CA   2 Fe(II)-[cytochrome c] + 2 H(+) + S-sulfosulfanyl-L-cysteinyl-[SoxY
CA   protein].
CA   (2) 2 Fe(III)-[cytochrome c] + S-sulfanyl-L-cysteinyl-[SoxY protein] +
CA   thiosulfate = 2 Fe(II)-[cytochrome c] + 2 H(+) + S-(2-sulfodisulfanyl)-L-
CA   cysteinyl-[SoxY protein].
CC   -!- The enzyme is part of the Sox enzyme system, which participates in a
CC       bacterial thiosulfate oxidation pathway that produces sulfate.
CC   -!- It catalyzes two reactions in the pathway - early in the pathway it
CC       attaches a thiosulfate molecule to the sulfur atom of an L-cysteine
CC       of a SoxY protein; later it transfers a second thiosulfate molecule
CC       to a sulfane group that is already attached to the same cysteine
CC       residue.
