This entry represents the Walker B domain of RAD50 from eukaryotes and the prokaryotic homologue SbcCD complex subunit C. RAD50-ATPase forms a complex with Mre11-nuclease that detects and processes diverse and obstructed DNA ends. This domain is separated of the Walker A domain by a long coiled-coil domain and forms the nucleotide-binding domain (NBD) when the coiled coils fold back on themselves and bring together Walker A and B domains [1,2,3,4]. Two RAD50-NBDs forms heterotetramers with a Mre11 nuclease dimer that assemble as catalytic head module that binds and cleaves DNA in an ATP-dependent reaction. Through secondary structural analysis, it has been suggested that there is a wide structural conservation in the Rad50/SMC protein family as seen in structural similarities between RAD50's hook and ABC-ATPase MukB's elbow region [4].
