THERMOLABILE URACIL-DNA-GLYCOSYLASE, PROCESS FOR ITS PREPARATION AND USE FOR REMOVING URACIL FROM DNA

摘要

The invention concerns a thermolabile enzyme having uracil-DNA-glycosylase activity and characterized in particular by a high degree of purity, short half-life times and a content of less than 2 % contaminating foreign activities. The invention further concerns a process for preparing this enzyme and its use for removing the base uracil from DNA, in particular uracil-containing PCR products. The enzyme can be obtained from Gram-positive microorganisms such as, for example, Arthrobacter or Micrococcus.
