研究了一种与海星卵母细胞成熟有关的蛋白酶。胰蛋白酶样和胰凝乳蛋白酶样活性的650 kDa的蛋白酶在卵母细胞提取物中被发现增加两倍以上的影响下,1-甲基腺嘌呤在成熟过程中的胚泡破裂(GVBD)之前。亮肽素及其五种类似物对该蛋白酶的胰凝乳蛋白酶样活性而非胰蛋白酶样活性的抑制效力与对GVBD的抑制效力完全雅阁(Takagi Sawadaet al.(1989). Dev. 133,609 -612)。这些结果表明,胰凝乳蛋白酶样活性的650 kDa的蛋白酶(最有可能是20 S蛋白酶体)在海星卵母细胞成熟中起着关键作用。
A protease involved in oocyte maturation of a starfish,Asterina pectinifera, was explored. Trypsin-like and chymotrypsin-like activities of the 650-kDa protease in oocyte extract were revealed to increase more than twice under the influence of 1-methyladenine before germinal vesicle breakdown (GVBD) during maturation. The inhibitory potencies of leupeptin and its five analogs against the chymotrypsin-like activity, but not the trypsin-like activity, of this protease was well in accord with those against GVBD (Takagi Sawadaet al.(1989).Dev. Biol.133,609–612). These results indicate that the chymotrypsin-like activity of the 650-kDa protease (most probably 20 S proteasome) plays a key role in starfish oocyte maturation.
