Abstract
When S1 nuclease from Takadiastase was partially purified according to previously reported methods, it showed a 10 to 15 fold increase in specificactivity. Although such preparations were highly active on single-stranded DNA, they had traces of activity on native DNA and were contaminated by T1-RNase. The S1 enzyme was further purified by a single step of affinity chromatography on single-stranded DNA-acrylamide column to a final purification of 275-fold. This preparation was free of T1-RNase and had an absolute specificity for single-stranded DNA.Entities:
