Short name: Extracellular_endonuc_su_A

Domain relationships

Description

A family 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.
