Abstract
Two protamines, St1 and St2, were isolated from stallion sperm nuclei, where they represent about 75 and 25%, respectively, of the total basic protein complement. The primary structure of protamine St1 (49 residues; Mr approximately equal to 6600) has been determined. The structure of this protamine is compared to the amino-acid sequence of other mammalian protamines already known.
摘要
从公马精子细胞核中分离出了两种鱼精蛋白，即St1和St2，它们分别占总碱性蛋白总量的约75%和25%。已确定了鱼精蛋白St1（49个残基；Mr约等于6600）的一级结构。将这种鱼精蛋白的结构与其他已知哺乳动物鱼精蛋白的氨基酸序列进行了比较。
