TST (gene)


Thiosulfate sulfurtransferase is an enzyme that in humans is encoded by the TST gene.
The product of this gene is a mitochondrial matrix enzyme that is encoded by the nucleus. It may play roles in cyanide detoxification, the formation of iron-sulfur proteins, and the modification of sulfur-containing enzymes.
The gene product contains two highly conservative domains, suggesting these domains have a common evolutionary origin.
