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的卜软腐的果胶酸内裂解酶。

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

与果胶酸裂解酶的底相同。卜软腐欧的多个亚种产生此酶，但菊欧不产生。
