FunFam 32: L-cysteine S-thiosulfotransferase subunit SoxA

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

L-cysteine S-thiosulfotransferase. [EC: 2.8.5.2]
(1) [SoxY protein]-L-cysteine + thiosulfate + 2 ferricytochrome c = [SoxY protein]-S-sulfosulfanyl-L-cysteine + 2 ferrocytochrome c + 2 H(+). (2) [SoxY protein]-S-sulfanyl-L-cysteine + thiosulfate + 2 ferricytochrome c = [SoxY protein]-S-(2-sulfodisulfanyl)-L-cysteine + 2 ferrocytochrome c + 2 H(+).
  • The enzyme is part of the Sox enzyme system, which participates in a bacterial thiosulfate oxidation pathway that produces sulfate.
  • It catalyzes two reactions in the pathway - early in the pathway it attaches a thiosulfate molecule to the sulfur atom of an L-cysteine of a SoxY protein; later it transfers a second thiosulfate molecule to a sulfane group that is already attached to the same cysteine residue.
