RHOD

Rhodanese Homology Domain
RHOD
SMART accession number:SM00450
Description: An alpha beta fold found duplicated in the Rhodanese protein. The the Cysteine containing enzymatically active version of the domain is also found in the CDC25 class of protein phosphatases and a variety of proteins such as sulfide dehydrogenases and stress proteins such as Senesence specific protein 1 in plants, PspE and GlpE in bacteria and cyanide and arsenate resistance proteins. Inactive versions with a loss of the cysteine are also seen in Dual specificity phosphatases, ubiquitin hydrolases from yeast and in sulfuryltransferases. These are likely to play a role in protein interactions.
Interpro abstract (IPR001763):

Rhodanese, a sulphurtransferase involved in cyanide detoxification (see IPR001307 ) shares evolutionary relationship with a large family of proteins [ (PUBMED:9733650) ], including

  • Cdc25 phosphatase catalytic domain.
  • non-catalytic domains of eukaryotic dual-specificity MAPK-phosphatases.
  • non-catalytic domains of yeast PTP-type MAPK-phosphatases.
  • non-catalytic domains of yeast Ubp4, Ubp5, Ubp7.
  • non-catalytic domains of mammalian Ubp-Y.
  • Drosophila heat shock protein HSP-67BB.
  • several bacterial cold-shock and phage shock proteins.
  • plant senescence associated proteins.
  • catalytic and non-catalytic domains of rhodanese (see IPR001307 ).

Rhodanese has an internal duplication. This domain is found as a single copy in other proteins, including phosphatases and ubiquitin C-terminal hydrolases [ (PUBMED:8702871) ].
