Purification and characterization of two endopolygalacturonases secreted during the early stages of the saprophytic growth of Sclerotinia sclerotiorum

Two endopolygalacturonases (endo-PGs) secreted at the early stage of cultures of Sclerotinia sclerotiorum grown on polygalacturonate medium, were purified to apparent homogeneity, using ion exchange chromatography. They are glycoproteins of an apparent weight of 42 and 41.5 kDa and a pI of 4.8. The...
