title: Purification of a lysosomal DNase from Drosophila melanogaster.
abstract: An acid DNase was purified from Drosophila melanogaster till apparent homogeneity by six consecutive chromatographic steps. The enzyme is a lysosomal DNase, because it is glycosylated and carries 1.8-2.4 mol of mannose-6-phosphate/mol of enzyme. The enzyme is fully active without any divalent cation and introduces single stranded nicks into a supercoiled DNA.
