Inhibitors

Inhibitors Comment Organism Structure
polygalacturonase-inhibiting proteins from Solanum lycopersicum stem cell wall extract, comparison of inhibition of polygalacturonases of wild-type and non-virulent phenotype conversion mutant strains of Ralstonia solanacearum by polygalacturonase-inhibiting proteins, PGIPs, from tomato stems. Polygalacturonase activity of the phenotype conversion mutant strain increases about 5 h earlier than the wild-type, and is up to 35 times higher in media supplemented with two different tomato stem extracts or polygalacturonic acid, compared to the wild-type, and generally 4-8 times higher across test media and time Ralstonia solanacearum

General Information

General Information Comment Organism
additional information the wild-type strain ToUdk2 contains endo-PG PehA, EC 3.2.1.15, and exo-PGs PehB and PehC, EC 3.2.1.67, while the PC mutant has mainly endo-PG activity. Endo- and exo-PG synthesis is governed by a sensitive regulatory network, which, in interaction with inhibitory polygalacturonase-inhibiting proteins and cell wall degradation products, leads to generation or avoidance of elicitor-active oligomers, and, thus, may contribute to the development of the compatible or incompatible interaction Ralstonia solanacearum
