A cysteine proteinase inhibitor with acidic isoelectric point (pI = 4.7-5.0) was found in human seminal plasma. Its apparent molecular mass is 16 kDa. It inhibits cysteine proteinases like ficin, cathepsin H, cathepsin B and papain. The inhibitory activity of seminal plasma against ficin is almost the same as that of human serum.
在人类精浆中发现了一种等电点呈酸性（pI = 4.7 - 5.0）的半胱氨酸蛋白酶抑制剂。其表观分子量为16 kDa。它能抑制诸如无花果蛋白酶、组织蛋白酶H、组织蛋白酶B和木瓜蛋白酶等半胱氨酸蛋白酶。精浆对无花果蛋白酶的抑制活性与人类血清的抑制活性几乎相同。
