Abstract
Enzymatic activation of Clostridium perfringens epsilon prototoxin removed a small basic part of the molecule, causing a slight change in molecular weight (32,700 to 31,200) and a large change in isoelectric point (from pH 8.02 into fractions of 5.36 and 5.74).
摘要
产气荚膜梭菌ε原毒素的酶促激活去除了分子的一个小碱性部分，导致分子量略有变化（从32,700变为31,200），等电点发生较大变化（从pH 8.02变为5.36和5.74）。
