Nuclease S1 from Aspergillus oryzae has been used in a study to assess a biochemical method for mapping mutational alterations in DNA. It has also been used in a study to investigate the DNA damage and repair in a γ-irradiated rat brain tumor.
The Nuclease S1 enzyme from Aspergillus oryzae has the ability to degrade single-stranded oligonucleotides composed of either deoxynucleotides or ribonucleotides.
SI nuclease from Aspergillus oryzae can generate double-stranded DNA breaks in response to DNA nicks or abasic sites.
