Cannabis Compound Identification
Common NameSelenocysteine
DescriptionSelenocysteine, also known as 3-seleno-alanine, 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. Selenocysteine is a very strong basic compound (based on its pKa). Selenocysteine exists in all living species, ranging from bacteria to humans. Within humans, selenocysteine participates in a number of enzymatic reactions. In particular, selenocysteine can be converted into L-alanine and hydrogen selenide; which is catalyzed by the enzyme selenocysteine lyase. In addition, selenocysteine and 2-ketobutyric acid can be biosynthesized from selenocystathionine through the action of the enzyme cystathionine gamma-lyase. In humans, selenocysteine is involved in selenoamino acid metabolism. The L-enantiomer of selenocysteine. Selenocysteine is expected to be in Cannabis as all living plants are known to produce and metabolize it.

Gene Name:
TXNRD2
Uniprot ID:
Q9NNW7
Molecular weight:
56506.275
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.
