[The isolation and partial purification of 2 DNA-dependent DNA polymerases from Acholeplasma laidlawii PG-8].
Two forms of DNA-dependent DNA-polymerase have been isolated and partially purified from the limited amount of biomass of cells Acholeplasma laidlawii PG-8, a typical representative of genus Acholeplasmataceae, as a result of successive chromatography on the columns with DEAE-cellulose DE-52 and Green A-sepharose. The first form of DNA-polymerase is eluted from the ion-exchange column with NaCl concentration of 0.1 M from the column with Green A-sepharose of 0.27 M, while the second form-with NaCl concentrations of 0.6 and 0.4 M, respectively. The both enzymatic activities are able to implement DNA synthesis. The conditions of DNA-polymerase production proved to be rather convenient for isolation of the concentrated and highly active enzymes.
