title: Purification and characterization of a collagenolytic enzyme produced by Rathayibacter sp. strains isolated from cultures of Clavibacter michiganensis subsp. michiganensis.
abstract: We show in this work that collagenolytic Rathayibacter sp. are isolated with phytopathogenic Clavibacter michiganensis subsp. michiganensis strains. The Rathayibacter strains isolated all produced collagenases. One of these collagenases (from the strain 1715) was purified by ammonium sulphate precipitation, DEAE cellulose and Sephadex G 200 chromatography. Characterization of the enzyme showed that it is a true collagenase which is able to degrade both native collagen, gelatin and probably other proteins from plants sharing sequence homologies with collagen.
