| 摘 要： | 昆虫杆状病毒的蜕皮甾体尿苷二磷酸葡糖转移酶（ecdysteroid UDP-glucosyltransferase, EGT）能催化UDP-糖基连接到蜕皮甾体上，使之失活，从而阻止或推迟蜕皮，有利于病毒复制，所以缺失egt基因的病毒能改良杀虫效果，如加速死亡和减少摄食量等.最近几年的研究进展主要集中在基因和蛋白质的一级结构、酶催化反应、以及对宿主的生物学功能等几方面.

| Abstract: | Insect baculovirus-encoded ecdysteroid UDP-glucosyltransferase (EGT) are not essential enzymes which catalyze the conjugation of ecdysteroids with UDP-glucose. In vivo, the sugar conjugation of ecdysteroids by EGT causes suppression of host molting. The deletion of egt gene actually improves the pesticidal properties of the baculovirus. Insects infected by an egt-minus virus display reduce feeding and earlier death than those infected by wild-type virus. The recent advances in the studies of the egt gene and protein, EGT-catalyzed conjugation, EGT effects on host development and suvival as well as biological role of EGT are introduced. |
