NucA nuclease Digestion of DNA.

NucA nuclease Digestion of DNA.

2 μg plasmid DNA was incubated with increasing amounts (ng/mL) of RecombinantS. marcescensNucA nuclease (Catalog # 10038-NA) in 50 mM Tris (pH 8.0) and 1 mM MgCl2 for 30 minutes at room temperature. Samples were analyzed by agarose gel electrophoresis and DNA was visualized by ethidium bromide staining.

Background: NucA nuclease

Serratia marcescens endonuclease, is a non-specific nuclease that degrades both single- and double-stranded nucleic acids, including DNA and RNA, but exhibits no proteolytic activity (1); therefore, it is ideal for the removal of nucleic acid contaminants from protein samples and applications where complete digestion of nucleic acids is desirable. NucA is also commonly used in bioprocessing applications to reduce viscosity of samples caused by genomic DNA. The optimum pH for enzyme activity is found to be 8.0-9.2. It hydrolyzes internal phosphodiester bonds between nucleotides in nucleic acids to produce 5'-monophosphate oligonucleotides of 3-8 bases in length (2). The active enzyme is a homodimer with two disulfide bonds in each monomer that are crucial to the enzyme activity and stability (3). The absolute activity of the recombinant enzyme is measured by a phosphatase coupled assay (4), where the 5'-phosphate of oligosaccharides generated by the enzyme is further released by non-specific alkaline phosphatase and quantitated by Malachite reagents (5).
