Biochem/physiol Actions

Metabolite in cysteine and methionine metabolism, important intermediate in the mercaptopyruvate pathway, in which cysteine or aspartate transaminase catalyzes the transamination from cysteine to 3-mercaptopyruvate and then 3-mercaptopyruvate sulfurtransferase catalyzes the transsulfuration from 3-mercaptopyruvate to pyruvate, a process contributing to maintain the cellular redox status. It is a substrate for L-lactate dehydrogenase A chain, 3-mercaptopyruvate sulfurtransferase, Aspartate aminotransferase (mitochondrial), L-lactate dehydrogenase C chain, L-lactate dehydrogenase A-like 6A, Aspartate aminotransferase (cytoplasmic), L-lactate dehydrogenase B chain and L-lactate dehydrogenase A-like 6B.

Packaging

Genome mining and biochemical analyses have shown that Leishmania major possesses two pathways for cysteine synthesis--the de novo biosynthesis pathway comprising SAT (serine acetyltransferase) and CS (cysteine synthase) and the RTS (reverse trans-sulfuration) pathway comprising CBS (cystathionine beta-synthase) and CGL

The current suite of Food and Drug Administration (FDA) approved antidotes (i.e., sodium nitrite, sodium thiosulfate, and hydroxocobalamin) are effective for treating cyanide poisoning, but individually, each antidote has major limitations (e.g., large effective dosage or delayed onset of action).

3-Mercaptopyruvate sulfurtransferase (3MST) is an important enzyme for the synthesis of hydrogen sulfide (H2S) in the brain. We present here data that indicate an exclusively localization of 3MST in astrocytes. Regional distribution of 3MST activities is even and unremarkable. Following
