Abstract
DNase activities in different protein fractions of Frankia strain R43 were studied. The extracellular and the cell wall-associated fractions revealed the presence of exo- and endonucleolytic enzymes, but none w as detected in the cytoplasmic fraction. The strongest DNase hydrolysi s was found in the extracellular fraction, in which six DNases were de tected by sodium dodecyl sulfate-polyacrylamide gel electrophoresis.
