ATP-dependent helicase/deoxyribonuclease subunit B (ADDB) forms a heterodimer with ADDA which acts as both an ATP-dependent DNA helicase and an ATP-dependent single-stranded exonuclease, acting in both directions. This entry represents the N-terminal domain of ADDB, which contains the Walker A motif involved in ATP binding [1,2].	Domain

The Rep family helicases are composed of four structural domains. The Rep family function as dimers. REP helicases catalyse ATP dependent unwinding of double stranded DNA to single stranded DNA. Swiss:P23478, Swiss:P08394 have large insertions near to the carboxy-terminus relative to other members of the family.	Domain
