The method of purification Erwinia carotovora recombinant L-asparaginase, expressed in E.coli, including ultrasonic disintegration of biomass, fractionation ammonium sulfate and column chromatography on СМ- or SP-Sepharose has been developed. According to SDS-PAAGE the enzyme preparation was homogeneous, its specific activity and yield consist respectively about 620 IU/mg of protein and 75%. Physical-chemical and structural properties of recombinant Erwinia carotovora L-asparaginase are similar to the enzymes from the wild strains Erwinia carotovora and recombinant L-asparaginase Erwinia chrysanthemi.
