Uncharacterized nucleases similar to lambda phage exonuclease; This model characterizes a diverse set of nucleases such as alkaline exonuclease from Laribacter hongkongensis, lambda phage exonuclease, or a Cas4-like protein from the Mimivirus virophage resistance element system. They belong to a superfamily of nucleases including very short patch repair (Vsr) endonucleases, archaeal Holliday junction resolvases, MutH methyl-directed DNA mismatch-repair endonucleases, and catalytic domains of many restriction endonucleases, such as EcoRI, BamHI, and FokI.

504-642 4.67e-05

YqaJ-like viral recombinase domain; This protein family is found in many different bacterial species but is of viral origin. The protein forms an oligomer and functions as a processive alkaline exonuclease that digests linear double-stranded DNA in a Mg(2+)-dependent reaction, It has a preference for 5'-phosphorylated DNA ends. It thus forms part of the two-component SynExo viral recombinase functional unit.
