Cannabis Compound Identification
Common NameL-Methionine
DescriptionL-Methionine, also known as acimethin or H-met-H, belongs to the class of organic compounds known as methionine and derivatives. Methionine and derivatives are compounds containing methionine or a derivative thereof resulting from reaction of methionine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. The L-enantiomer of methionine. L-Methionine is a drug which is used for protein synthesis including the formation of same, l-homocysteine, l-cysteine, taurine, and sulfate. L-Methionine is a very strong basic compound (based on its pKa). L-Methionine exists in all living species, ranging from bacteria to humans. Outside of the human body, L-Methionine is found, on average, in the highest concentration within a few different foods, such as milk (cow), beluga whales, and smelts and in a lower concentration in white cabbages, wax gourds, and coconuts. L-Methionine has also been detected, but not quantified in, several different foods, such as pepper (c. chinense), acerola, grass pea, oxheart cabbages, and sherries. This could make L-methionine a potential biomarker for the consumption of these foods. L-Methionine is a potentially toxic compound. L-Methionine, with regard to humans, has been found to be associated with several diseases such as autism, leukemia, obesity, and heart failure; L-methionine has also been linked to the inborn metabolic disorder celiac disease. L-Methionine is expected to be in Cannabis as all living plants are known to produce and metabolize it.

Enzymes

Enzyme Details
1. Methionine synthase
General function:
Involved in cobalamin binding
Specific function:
Catalyzes the transfer of a methyl group from methyl-cobalamin to homocysteine, yielding enzyme-bound cob(I)alamin and methionine. Subsequently, remethylates the cofactor using methyltetrahydrofolate (By similarity).

Enzyme Details
5. Arsenite methyltransferase
General function:
Involved in methyltransferase activity
Specific function:
Catalyzes the transfer of a methyl group from AdoMet to trivalent arsenicals producing methylated and dimethylated arsenicals. It methylates arsenite to form methylarsonate, Me-AsO(3)H(2), which is reduced by methylarsonate reductase to methylarsonite, Me-As(OH)2. Methylarsonite is also a substrate and it is converted into the much less toxic compound dimethylarsinate (cacodylate), Me(2)As(O)-OH (By similarity).

6. Indolethylamine N-methyltransferase
General function:
Involved in methyltransferase activity
Specific function:
Functions as thioether S-methyltransferase and is active with a variety of thioethers and the corresponding selenium and tellurium compounds, including 3-methylthiopropionaldehyde, dimethyl selenide, dimethyl telluride, 2-methylthioethylamine, 2-methylthioethanol, methyl-n-propyl sulfide and diethyl sulfide. Plays an important role in the detoxification of selenium compounds (By similarity). Catalyzes the N-methylation of tryptamine and structurally related compounds.
