Aspergillus oryzae

Applications

• Catalyzes degradation of single-stranded nucleic acids into oligonucleotides and 5-mononucleotides (1)
• Cleaves both single-stranded DNA and RNA, with stronger DNAse activity
• Double-stranded DNA, double-stranded RNA and DNA-RNA hybrids are resistant to degradation at moderate enzyme concentration
• Capable of cleavage of double-stranded nucleic acids at nicks, mismatches and small gaps (2)
• Relaxes/linearizes supercoiled plasmids
• Removes protruding single-stranded ends
• Can generate double-stranded DNA breaks in response to DNA nicks abasic sites
• Used for S1 mapping of nucleic acids
• Requires Zn²+ ions for activity
• The enzyme is active up to 65°C
