Polygalacturonases Release Cell-Wall-bound Proteins 1

PMCID: PMC542295  PMID: 16659753

Abstract

Purified polygalacturonases from two fungi released proteins from wall fractions prepared from three plant species. Peroxidase activity was associated with the proteins released from the cell walls, and several of the protein fractions released contained hydroxyproline. Cellulase, purified free of pectic enzyme activity, was ineffective in releasing cell wall proteins. Specific inhibition of endopolygalacturonase activity prevented release of the proteins.
