Biochem/physiol Actions

An analog of methionine that interferes with the normal methylation of DNA and other methylation pathways, and induces pancreatic toxicity and liver cancer. However, in animal studies, it has also been shown to act synergistically with methionine-depletion to block the growth and metastasis of methionine-dependent tumors.

Methionine gamma-lyase (MGL) catalyzes the degradation of L-methionine to alpha-ketobutyrate, methanethiol and ammonia. The Arabidopsis (Arabidopsis thaliana) genome includes a single gene (At1g64660) encoding a protein (AtMGL) with approximately 35% identity to bacterial and protozoan MGLs. When overexpressed in Escherichia
