The best studied inducible and repressible enzyme in phytopathogenic prokaryotes is endo-pectate lyase in E. carotovora.
Polygalacturonase has the same substrate specificity as pectate lyase. This enzyme is produced by Erwinia carotovora subspp. but not by Erwinia chyrsanthemi.
CDW also increased the activity of phenylalanine ammonia lyase (PAL), expres-sion of a P. ginseng squalene epoxidase (sqe) gene and saponin synthesis.
Moreover, the activities of isocitrate lyase and isocitrate dehydrogenase in the 0 P-treated cells were 1.48 and 0.75 times higher than in the control at day 8 of the treatment.
