Metabolite Identification
Common NameThiocyanate
DescriptionThiocyanate is analogous to the cyanate ion, [OCN]-, wherein oxygen is replaced by sulfur. [SCN]- is one of the pseudohalogens, due to the similarity of its reactions to that of halide ions. Thiocyanate was formerly known as rhodanide (from a Greek word for rose) because of the red color of its complexes with iron. Thiocyanates are typically colorless. Cyanide ions can react with cystine to yield thicocyanate. This reaction occurs to a slight extent even in neutral solution, but is more pronounced in alkaline solutions of cystine. In addition to this non-enzymatic route, cyanide produced in vivo can be converted in part to thiocyanate by sulfur transferase systems. The thiocyanate ion can be oxidized at acid pH by hydrogen peroxide to generate sulfate and cyanide. The reaction is catalyzed by hemoglobin acting as a peroxidase.

A study shows that thiocyanate has a protective effect in lung in cystic fibrosis, and an anti-inflammatory effect in arterial endothelial cells, a neuronal cell line, and a pancreatic beta cell line (PMID: 19918082 ). Thiocyanate has been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821 ).

General function:
Involved in thiosulfate sulfurtransferase activity
Specific function:
Transfer of a sulfur ion to cyanide or to other thiol compounds. Also has weak rhodanese activity. May have a role in cyanide degradation or in thiosulfate biosynthesis.
Gene Name:

2. Thiosulfate sulfurtransferase
General function:
Involved in thiosulfate sulfurtransferase activity
Specific function:
Formation of iron-sulfur complexes, cyanide detoxification or modification of sulfur-containing enzymes. Other thiol compounds, besides cyanide, can act as sulfur ion acceptors. Also has weak mercaptopyruvate sulfurtransferase (MST) activity (By similarity). Together with MRPL18, acts as a mitochondrial import factor for the cytosolic 5S rRNA. Only the nascent unfolded cytoplasmic form is able to bind to the 5S rRNA.
