Abstract
Four classes of Xanthomonas campestris mutants were identified with respect to pectate lyase. Pectate lyase production in the wild-type and classes I and IIb mutants was partially dependent on the growth-phase whereas in classes IIa and III it was totally dependent. Enzyme activity in some of the mutants was constitutive and resistant to catabolite repression.
摘要
四类黄单胞菌突变体在果胶裂解酶方面得到了鉴定。野生型和 I 类和 IIb 类突变体的果胶裂解酶的产生部分依赖于生长阶段，而 IIa 和 III 类则完全依赖于生长阶段。一些突变体的酶活性是组成型的，并且不受分解代谢物阻遏的影响。
