Metabolite Identification
Common NameMorphine-6-glucuronide
DescriptionMorphine-6-glucuronide (M6G) is a major active metabolite of morphine, and as such is the molecule responsible for much of the pain-relieving effects of morphine (and thus heroin). M6G is formed from morphine by the enzyme UDP-Glucuronosyltransferase-2B7 (UGT2B7). M6G can accumulate to toxic levels in kidney failure.

Enzymes

General function:
Involved in transferase activity, transferring hexosyl groups
Specific function:
UDPGTs are of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isozyme has glucuronidating capacity with steroid substrates such as 5-beta-androstane 3-alpha,17-beta-diol, estradiol, ADT, eugenol and bile acids. Only isoform 1 seems to be active.

General function:
Involved in transferase activity, transferring hexosyl groups
Specific function:
UDPGTs are of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isozyme is active on polyhydroxylated estrogens (such as estriol, 4-hydroxyestrone and 2-hydroxyestriol) and xenobiotics (such as 4-methylumbelliferone, 1-naphthol, 4-nitrophenol, 2-aminophenol, 4-hydroxybiphenyl and menthol). It is capable of 6 alpha-hydroxyglucuronidation of hyodeoxycholic acid.

General function:
Involved in transferase activity, transferring hexosyl groups
Specific function:
UDPGT is of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. Its unique specificity for 3,4-catechol estrogens and estriol suggests it may play an important role in regulating the level and activity of these potent and active estrogen metabolites. Is also active with androsterone, hyodeoxycholic acid and tetrachlorocatechol (in vitro).

General function:
Involved in transferase activity, transferring hexosyl groups
Specific function:
UDPGTs are of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isozyme displays activity toward several classes of xenobiotic substrates, including simple phenolic compounds, 7-hydroxylated coumarins, flavonoids, anthraquinones, and certain drugs and their hydroxylated metabolites.
