It catalyzed the glucuronidation of not only phenolic xenobiotics such as 4-nitrophenol, 1-naphthol, and eugenol but also serotonin, which is an endogenous compound.
After removal of the detergent (Emulgen 911), the transferase activity was stimulated by various phospholipids, about 10-fold activation being attained with phosphatidylcholine and lysophosphatidylcholine.

Effect of potent cytochrome P-448 inducer, 1-m-tolueneazo-2-naphthol (m-TAN) on hepatic microsomal UDP-glucuronyl-transferase (UDPGT) activity was studied.
The UDPGT activities towards p-nitrophenol, 1-naphthol and chloramphenicol were increased up to 6,2.5 and 1.8 folds of control levels respectively, in microsomes from m-TAN treated rats. 3-Methylcholanthrene, on the other hand, caused 4 and 2 fold increase in UDPGT activities towards p-nitrophenol and 1-naphthol, respectively, but did not cause significant increase in UDPGT activity towards chloramphenicol.

The activities of the ethoxycoumarin O-deethylase (ECOD), epoxide hydrolase (EH), UDP-glucuronyl transferase (GT), glutathione S-transferase (GST), acetyl transferase (AT) and sulphotransferase (ST) were measured in 6 liver, 8 lung, 8 kidney, 8 intestinal mucosa and 22 urinary bladder mucosa specimens from human subjects.
EH and GT were studied with styrene oxide and 1-naphthol, respectively, as substrates, GST, AT and ST were studied with benzo (a) pyrene-4,5-oxide, p-aminobenzoic acid and 2-naphthol, respectively. 2.

We examined the effect of phenobarbital on bilirubin UDP-glucosyltransferase and the UDP-glucuronyltransferase activities towards bilirubin, 4-nitrophenol, and 1-naphthol using native rat liver microsomes with verified vesicle integrity.
In contrast, none of the transferase activities tested were significantly enhanced by phenobarbital treatment when the enzymic activities were assayed in sealed microsomes.

The enzyme appeared to follow an ordered sequential bireactant mechanism in which 1-naphthol and UDP-glucuronic acid (UDPGlcUA) are the first and second binding substrates and UDP and 1-naphthol glucuronide the first and second products, respectively.

This study was conducted to evaluate UDP-glucuronosyl-transferase (UDP-GT) activity, UDP-glucuronic acid (UDP-GA) concentration, and UDP-glucose (UDPG) concentration in the rat intestine and liver following oral administration of butylated hydroxyanisole (BHA), benzo [a] pyrene (BaP), 3-methylcholanthrene (3MC), phenobarbital (PB), pregnenolone-16 alpha-carbonitrile (PCN), 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), or trans-stilbene oxide (TSO).

UDP-glucuronyltransferase activity of neonatal-chick liver or phenobarbital-treated chick-embryo liver catalysed the glucuronidation of 1-naphthol, 4-nitrophenol and 2-aminophenol.
Liver microsomal transferase activity towards the three phenols was increased approx. 20-50-fold by phenobarbital treatment of chick embryos or by transfer of liver cells into tissue culture.

UDP-glucuronyl-transferase activity in renal microsomes prepared from male and female rats toward p-nitrophenol was 0.21 +/- 0.09 nmol/min/mg of protein and 0.91 +/- 0.02 nmol/min/mg of protein, respectively.

In general 4-nitrophenol glucuronidation was more effectively inhibited than that of 1-naphthol, bilirubin or testosterone. 2-(1-Naphthyl) ethyl-UDP and 2,2,2-(triphenyl) ethyl-UDP were the most effective inhibitors.
The various UDP derivatives showed differences in their abilities to inhibit the glucuronidation of the four acceptor substrates, supporting the concept that the different forms of UDP-glucuronosyl transferase have different active sites.

CHAPS alone also generated similarly sized particles under conditions in which UDP glucuronosyltransferase activity toward 1-naphthol and morphine was two to about twenty times greater, respectively, than with the combination of detergents.
This finding suggests that the zwitterionic CHAPS is superior to other detergent systems for studies concerned with the purification of transferase enzymes, a microsomal system in which investigation of the number of different forms has been hampered by the instability of the enzyme upon solubilization and subsequent manipulation.

All five 2-substituted pyridines investigated increased rat hepatic UDP-glucuronosyltransferase activities toward three aglycones (morphine, p-nitrophenol, and 1-naphthol) without inducing cytochrome P450.

However, the effects of phospholipids on these enzymes were extremely different. 1-Naphthol glucuronizing activity of GT-1 was increased 7.5-8-fold by lysophosphatidylcholine, but the activity of GT-2 was increased only 3-3.6-fold.
The transferase activity of GT-1 toward 4-methylumbelliferone was increased 2-2.5-fold by dilauroylphosphatidylcholine, but that of GT-2 was reduced, while its 4-nitrophenol glucuronidation activity was increased 1.5-fold by the phospholipid.
