Abstract
Dodecahedral crystals of chicken pepsinogen have been prepared, one perfect cystal having the dimensions 0.090mm x 0.086mm x 0.009mm. The derived pepsin crystakkized in the form of flat plates, often with one rounded end. The dimensions of one such crystal wer 0.076mm x 0.043mm. Both types of protein crystals showed full enzymic or potential enzymic activity.
摘要
已制备出鸡胃蛋白酶原的十二面体晶体，其中一个完美晶体的尺寸为0.090毫米×0.086毫米×0.009毫米。衍生出的胃蛋白酶以平板形式结晶，通常一端呈圆形。一个这样的晶体尺寸为0.076毫米×0.043毫米。这两种蛋白质晶体均表现出完全的酶活性或潜在的酶活性。
