mdeA recombinant protein
Background: Methionine gamma-lyase (EC from Pseudomonas putida is a PLP-dependent enzyme which plays a central role in sulfur amino acid metabolism. METase catalyzes the alpha, gamma-elimination of methionine to alpha-ketobutyrate, methanethiol, and ammonia. METase also catalyzes the alpha, gamma-elimination of other sulfur containing amino acids, such as homocysteine, cysteine. Because of its ability to deplete methionine, METase has been considered as a viable component of cancer therapeutics against methionine-dependent tumor cells. METase has also been utilized to design drug targets for the infectious diseases caused by parasitic protozoa and anaerobic periodontal bacteria.

UniProt Comments for mdeA
Catalyzes the alpha,gamma-elimination of L-methionine to produce methanethiol, 2-oxobutanoate and ammonia (PubMed:8586629, PubMed:6742420). Is involved in L-methionine catabolism (PubMed:9190812). In fact, shows a multicatalytic function since it also catalyzes gamma-replacement of L-methionine with thiol compounds, alpha,gamma-elimination and gamma-replacement reactions of L-homocysteine and its S-substituted derivatives, O-substituted-L-homoserines and DL-selenomethionine, and, to a lesser extent, alpha,beta-elimination and beta-replacement reactions of L-cysteine, S-methyl-L-cysteine, and O-acetyl-L-serine (PubMed:6742420, PubMed:22785484). Also catalyzes deamination and gamma-addition reactions of L-vinylglycine (PubMed:6742420). Thus, the enzyme is able to cleave C-S, C-Se, and C-O bonds of sulfur, selenium, and oxygen amino acids, respectively (PubMed:6742420, PubMed:22785484).
