3-mercaptopyruvate sulfurtransferase


Definition: an enzyme that is a part of the cysteine catabolic pathway; it catalyzes the conversion of 3-mercaptopyruvate to pyruvate and H2S; a deficiency of this enzyme will result in elevated urine concentrations of 3-mercaptopyruvate as well as of 3-mercaptolactate, both in the form of disulfides with cysteine.
