title: Molecular cloning and nucleotide sequence of the pectate lyase gene from Pseudomonas marginalis N6301.
abstract: Pectate lyase was purified approximately 29-fold to electrophoretic homogeneity from Pseudomonas marginalis N6301. A pectate lyase (PL; EC4.2.2.2) gene of the strain was cloned and expressed in Escherichia coli. The nucleotides of the PL gene (pel) were sequenced. An open reading frame that encodes a polypeptide (molecular weight: 40,812) composed of 380 amino acids including a 29 amino acid signal peptide was assigned. The structural gene of pel consisted of 1140 base pairs. The nucleotide sequence of the 5'-flanking region of pel showed a consensus sequence of the promoter region of the pectin lyase gene (pnl) in P. marginalis N6301, a Pribnow box, and a ribosome binding site as found in E. coli.
