Comparative analysis of the five major Erwinia chrysanthemi pectate lyases: enzyme characteristics and potential inhibitors.


In Erwinia chrysanthemi 3937, pectate lyase activity mainly results from the cumulative action of five major isoenzymes, PelA to PelE. Comparison of their amino acid sequences revealed two families, PelB-C and PelA-D-E. Molecular cloning permitted expression of the different pel genes in Escherichia coli and the isolation of each Pel independently from the… (More)
