WebS1 Nuclease degrades single-stranded nucleic acids, releasing 5'-phosphoryl mono- or oligonucleotides. It is five times more active on DNA than on RNA (1). S1 Nuclease also … WebS1 Nuclease is a single-strand-specific endonuclease that hydrolyzes single-stranded RNA or DNA into 5´ mononucleotides. The enzyme will hydrolyze single-stranded regions in duplex DNA such as loops and gaps. S1 Nuclease is stable at 65°C. Applications: Nuclease mapping techniques (1,2). Removal of single-stranded regions from double-stranded ...
WebS1 Nuclease is an endonuclease that specifically degrades single-stranded nucleic acids, including the single-stranded regions of duplex DNA, RNA, or DNA/RNA. S1 Nuclease preferentially targets DNA over RNA. This endonuclease can also introduce single-stranded nicks and breaks in duplex DNA, RNA, and DNA/RNA. WebThe structure of the active site in a metalloenzyme can be a key determinant of its metal ion binding affinity and catalytic activity. In this study, the conformational features of the Zn2+-binding H
