Molecular cloning, nucleotide sequence, and marker exchange mutagenesis of the exo-poly-alpha-D-galacturonosidase-encoding pehX gene of Erwinia chrysanthemi EC16.

Journal of bacteriology - 1 Sept 1990

He S Y, Collmer A

Abstract excerpt

The pehX gene encoding extracellular exo-poly-alpha-D-galacturonosidase (exoPG; EC 3.2.1.82) was isolated from a genomic library of the pectate lyase-deficient Erwinia chrysanthemi mutant UM1005 (a Nalr Kanr delta pelABCE derivative of EC16) by immunoscreening 2,800 Escherichia coli HB101 transformants with an antibody against exoPG protein. The cloned pehX gene was expressed highly from its own promoter in E....
