Abstract

A hypothesis, proposed 25 years ago, that there is selection against glycosylation in ruminant pancreatic ribonucleases by replacement of methionine to leucine in the ancestral carbohydrate attachment site Asn-Met-Thr at residues 34-36, was experimentally confirmed. The replacement of leucine at position 35 by methionine in bovine ribonuclease resulted in a three-fold relative increase in glycosylation when expressed in Chinese hamster ovary cells.

摘要

25年前提出的一个假说得到了实验证实,该假说认为反刍动物胰腺核糖核酸酶中存在针对糖基化的选择作用,其方式是在第34 - 36位残基的祖先碳水化合物连接位点天冬酰胺-蛋氨酸-苏氨酸(Asn-Met-Thr)处将蛋氨酸替换为亮氨酸。在牛核糖核酸酶中,第35位的亮氨酸被蛋氨酸取代后,在中国仓鼠卵巢细胞中表达时,糖基化相对增加了三倍。
