Abstract: | A deoxyribonuclease activity accompanies the competence substance isolated from transformableDiplococcus pneumoniae even in well purified fractions. The deoxyribonuclease seems to exhibit a rather different kind of activity from the one found as a major nuclease in a partially purified competence substance. The products of interaction between the enzyme and double-stranded DNA would indicate that the enzyme might act as an “unwindase” on the double-stranded DNA. |
