3-mercaptopyruvate

3-mercaptopyruvate
The transaminated product of cysteine; formed in cysteine catabolism; elevated in individuals with a deficiency of m. sulfurtransferase.
- 3-mercaptopyruvate sulfurtransferase an enzyme that is a part of the cysteine catabolic pathway; it catalyzes the conversion of m. to pyruvate and H2S; a deficiency of this enzyme will result in elevated urine concentrations of m. as well as of 3-mercaptolactate, both in the form of disulfides with cysteine.
