Housefly UDP-glucosyltransferase activity towards p-nitrophenol was demonstrated in a system in vitro. The activity is localized in the microsomal fraction, requires UDP-glucose, is slightly stimulated by Mg2+ and is activated optimally over a wide range of detergent concentration. Phenobarbital increases the enzyme(s) activity about 3-fold, with p-nitrophenol as substrate, which differs from the corresponding mammalian glucuronyltransferase.
家蝇对对硝基苯酚的UDP-葡萄糖基转移酶活性在体外系统中得到了证实。该活性定位于微粒体部分,需要UDP-葡萄糖,受Mg2+轻微刺激,并且在很宽的去污剂浓度范围内能得到最佳激活。以对硝基苯酚为底物时,苯巴比妥可使该酶活性提高约3倍,这与相应的哺乳动物葡萄糖醛酸基转移酶不同。
