== Function ==
[https://www.uniprot.org/uniprot/MEGL_FUSNN MEGL_FUSNN] Catalyzes the alpha,gamma-elimination of L-methionine to produce methanethiol, 2-oxobutanoate and ammonia, and that of L-homocysteine (By similarity). Can also use L-cysteine as substrate, catalyzing its alpha,beta-elimination; this activity seems to only minimally contribute to the production of hydrogen sulfide (H2S) by F.nucleatum in the oral cavity, which is toxic for a large variety of cells in periodontal regions (PubMed:21798982).[UniProtKB:Q8L0X4]<ref>PMID:21798982</ref>
