Abstract
Calcium-dependent exonuclease activity was produced by sporulating cells of Bacillus subtilis 168. Nuclease activity was released into the culture medium at approximately the same time as sporulation proteases, and production of these enzymes was tied to DNA replication. Results suggest that nuclease production is a function of the spo0H locus.
摘要
枯草芽孢杆菌168的产孢细胞产生了钙依赖性核酸外切酶活性。核酸酶活性与孢子形成蛋白酶大约在同一时间释放到培养基中，并且这些酶的产生与DNA复制相关。结果表明核酸酶的产生是spo0H基因座的一个功能。
