Of the various exoproteins secreted by Erwinia carotovora subsp. carotovora strain 71, Pel1 is the major pectate lyase species with tissue macerating activity. Nucleotide sequencing of a 2.2-kb pel1+ DNA segment revealed a 1,122 base pair open reading frame which could encode pre-Pel1 of 374 amino acid residues. A signal peptide of 22 amino acid residues is present within the NH2-terminal region of pre-Pel1. Transcription of pel1 was initiated at the guanine residue 111 base pairs upstream of the start codon. Consensus sequences for the binding of KdgR, a negative regulatory factor known to control some of the E. chrysanthemi pectinases, flank the promoter of pel1. Although pel1 belongs to the pelBC family, it is more closely related to the pel genes of E. carotovora than to the pelBC genes of E. chrysanthemi.
