Methyl halide transferase (EC 2.1.1.165, MCT, methyl chloride transferase, S-adenosyl-L-methionine:halide/bisulfide methyltransferase, AtHOL1, AtHOL2, AtHOL3, HMT, S-adenosyl-L-methionine: halide ion methyltransferase, SAM:halide ion methyltransferase) is an enzyme with systematic name S-adenosylmethionine:iodide methyltransferase.[1][2][3][4][5][6] This enzyme catalyses the following chemical reaction
This enzyme contributes to the methyl halide emissions from Arabidopsis thaliana.
Chloride transfer
[edit | edit source]The salt marsh plant Batis maritima contains the enzyme methyl chloride transferase that catalyzes the synthesis of chloromethane (CH3Cl) from S-adenosine-L-methionine and chloride.[7] This protein has been purified and expressed in E. coli, and seems to be present in other organisms such as white rot fungi (Phellinus pomaceus),[2] red algae (Endocladia muricata), and the ice plant (Mesembryanthemum crystallinum), each of which is a known CH3Cl producer.[7][8]
