ID 3.1.21.6 DE CC-preferring endodeoxyribonuclease. AN 5'-CC-3'-preferring endodeoxyribonuclease. AN Streptomyces glaucescens exocytoplasmic endodeoxyribonuclease. AN Streptomyces glaucescens exocytoplasmic endonuclease. CA endonucleolytic cleavage to give 5'-phosphooligonucleotide end-products, CA with a preference for cleavage within the sequence CC. CC -!- Prefers CC sites in double-stranded circular and linear DNA. CC -!- Greater affinity for double-stranded than single-stranded DNA. CC -!- Produces nicks, generating double-stranded fragments with 5'- and/or CC 3'-protruding single-stranded tails. //
