FunFam 36: Thiosulfate dehydrogenase

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.

EC Term Annotations Evidence
Thiosulfate dehydrogenase. [EC: 1.8.2.2]
2 thiosulfate + 2 ferricytochrome c = tetrathionate + 2 ferrocytochrome c.
  • The enzyme catalyzes the reversible formation of a sulfur-sulfur bond between the sulfane atoms of two thiosulfate molecules, yielding tetrathionate and releasing two electrons.
  • In many bacterial species the enzyme is a diheme c-type cytochrome.
  • In a number of organisms, including Thiomonas intermedia and Sideroxydans lithotrophicus, a second diheme cytochrome (TsdB) acts as the electron acceptor.
  • However, some organisms, such as Allochromatium vinosum, lack TsdB.
  • The electron acceptor in these organisms may be the high-potential iron-sulfur protein (HiPIP).
