Two molecular forms of Xenopus hatching enzyme, 60kD and 40kD molecules, was obtained during preparation and purification. Both of them were verified as the hatching enzyme molecules, using anti GST UVS.2 antibody as the probe. 60kD molecule was digested or autodigested easily into 40kD molecule during purification. It was indicated that 40kD molecule was probably derived from 60kD molecule with its two CUB repeats lost, and the two CUB repeats may play an important role in recognizing and/or modifying of the molecular structure of vitelline envelope.

在分离纯化非洲爪蟾孵化酶时，得到了60kD和40kD两种分子，用孵化酶的特异性抗GST-UVS.2抗体进行Western杂交的结果证明二者均为孵化酶分子。60kD分子很不稳定，在纯化过程中极易降解，40kD分子可能是由60kD分子经过降解或自身降解丢失了两个CUB重复区而形成的，而CUB重复区很可能在对受精膜分子结构的修饰或改造中具有重要作用。
