果胶的

The best studied inducible and repressible enzyme in phytopathogenic prokaryotes is endo-pectate lyase in E. carotovora.

植病原原核生中研究得最清楚是卜软腐菌果胶酸内裂。

Polygalacturonase has the same substrate specificity as pectate lyase. This enzyme is produced by Erwinia carotovora subspp. but not by Erwinia chyrsanthemi.

与果胶酸裂底相。卜软腐欧氏菌多个亚种产生此，但菊欧氏菌不产生。
