摘要

研究了米曲霉休眠和萌发孢子中β-葡萄糖苷酶(EC 3.2.1.21)的分布。在休眠分生孢子和萌发分生孢子的表皮中发现了相当数量的结合型β-葡萄糖苷酶,并且随着萌发的进行,分生孢子中结合型与可溶性型的比例增加。结合酶不能被洗涤剂、EDTA、尿素、盐和β-1,3-葡聚糖酶去除,但超声处理是相当有效的。物理和化学性质表明,结合酶与可溶性酶相同。

Studies on the spore coats of Aspergillus oryzae

The distribution of β-glucosidase (EC 3.2.1.21) in dormant and germinating conidia of Aspergillus oryzae has been studied. A considerable amount of the bound β-glucosidase is found in the conidia coats of dormant and germinating conidia, and the ratio of bound form to soluble form in the conidia increases as germination proceeds. The bound enzyme is not removed by detergents, EDTA, urea, salts, and β-1,3-glucanase, but sonication is fairly effective. The physical and chemical properties show that the bound enzyme is identical to the soluble enzyme.
