This entry represents an uncharacterised domain found in several proteins, including DNA replication helicase Dna2, clustered regularly interspaced short palindromic repeats (CRISPR)-associated exonuclease Cas4 and putative RecB family exonuclease proteins [1]. Dna2 is a DNA replication factor with single-stranded DNA-dependent ATPase, ATP-dependent nuclease, (5'-flap endonuclease) and helicase activities. Cas4 has been shown to be a 5' to 3' single stranded DNA exonuclease in Sulfolobus solfataricus [2,3]. This entry also includes Solo-Cas4 from Methanosarcina mazei Go1 (Swiss:Q8PYI8), a high oligomeric Cas4-family nuclease that preferentially targets supercoiled dsDNA and is upregulated during stationary growth [4].
