摘要：

1. 1. Proacrosin and acrosin were quantitated in boar sperm which were incubated in ligated segments of gilt uteri and in buffer. 2. 2. Most of the proacrosin (70-80%) was converted into acrosin in sperm incubated in vivo for 120 min while less than 3% of the proacrosin was converted into acrosin in the control sperm. 3. 3. Electrophoretic comparison of the enzymatic activities in the sperm extracts to homogeneous m(inχ)-acrosin and mμ-acrosin suggested that the in vivo conversion sequence was: proacrosin → min(χ)-acrosin → mβacrosin. © 1979.
