DNA/RNA non-specific endonuclease superfamily
IPR044929
Definition
A superfamily of bacterial and eukaryotic endonucleases [ec:3.1.30] share the following characteristics: they act on both DNA and RNA, cleave double-stranded and single-stranded nucleic acids and require a divalent ion such as magnesium for their activity. A histidine has been shown PMID:8078761 to be essential for the activity of the Serratia marcescens nuclease. This residue is located in a conserved region which also contains an aspartic acid residue that could be implicated in the binding of the divalent ion.
