Cannabis Compound Identification

Common Name

Selenomethionine

Description

Selenomethionine, also known as sethotope, belongs to the class of organic compounds known as l-alpha-amino acids. These are alpha amino acids which have the L-configuration of the alpha-carbon atom. Selenomethionine is a very strong basic compound (based on its pKa). selenomethionine can be converted into se-adenosylselenomethionine and phosphoric acid through its interaction with the enzyme S-adenosylmethionine synthase. In humans, selenomethionine is involved in selenoamino acid metabolism. The L-enantiomer of selenomethionine. Selenomethionine is expected to be in Cannabis as all living plants are known to produce and metabolize it.

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).
Gene Name:: MTR
Uniprot ID:: Q99707
Molecular weight:: 140525.91

Enzyme Details

2. S-adenosylmethionine synthase isoform type-2

General function:: Involved in methionine adenosyltransferase activity
Specific function:: Catalyzes the formation of S-adenosylmethionine from methionine and ATP.
Gene Name:: MAT2A
Uniprot ID:: P31153
Molecular weight:: 43660.37

Enzyme Details

3. S-adenosylmethionine synthase isoform type-1

General function:: Involved in methionine adenosyltransferase activity
Specific function:: Catalyzes the formation of S-adenosylmethionine from methionine and ATP.
Gene Name:: MAT1A
Uniprot ID:: Q00266
Molecular weight:: 43647.6

Enzyme Details

4. Cystathionine gamma-lyase

General function:: Involved in pyridoxal phosphate binding
Specific function:: Catalyzes the last step in the trans-sulfuration pathway from methionine to cysteine. Has broad substrate specificity. Converts cystathionine to cysteine, ammonia and 2-oxobutanoate. Converts two cysteine molecules to lanthionine and hydrogen sulfide. Can also accept homocysteine as substrate. Specificity depends on the levels of the endogenous substrates. Generates the endogenous signaling molecule hydrogen sulfide (H2S), and so contributes to the regulation of blood pressure. Acts as a cysteine-protein sulfhydrase by mediating sulfhydration of target proteins: sulfhydration consists of converting -SH groups into -SSH on specific cysteine residues of target proteins such as GAPDH, PTPN1 and NF-kappa-B subunit RELA, thereby regulating their function.

5. Methionine--tRNA ligase, cytoplasmic

General function:: Involved in nucleotide binding
Specific function:: Not Available
Gene Name:: MARS
Uniprot ID:: P56192
Molecular weight:: 101114.925

Enzyme Details

6. Methionine adenosyltransferase 2 subunit beta

General function:: Involved in dTDP-4-dehydrorhamnose reductase activity
Specific function:: Non-catalytic regulatory subunit of S-adenosylmethionine synthetase 2 (MAT2A), an enzyme that catalyzes the formation of S-adenosylmethionine from methionine and ATP. Regulates the activity of S-adenosylmethionine synthetase 2 by changing its kinetic properties, rendering the enzyme more susceptible to S-adenosylmethionine inhibition.
