Impaired Induction and Self-Catabolite Repression of Extracellular Pectate Lyase in Erwinia chrysanthemi Mutants Deficient in Oligogalacturonide Lyase

The pectate lyase (PL; EC 4.2.2.2) secreted by the plant pathogen Erwinia chrysanthemi is induced and catabolite repressed by different concentrations of its own product, digalacturonic acid 4,5-unsaturated at the nonreducing end [u(GalUA)2]. Both activities of u(GalUA)2depend on its cleavage by oli...
