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].

This family represents the N-terminal region of MukB, one of a group of bacterial proteins essential for the movement of nucleoids from mid-cell towards the cell quarters (i.e. chromosome partitioning). The structure of the N-terminal domain consists of an antiparallel six-stranded beta sheet surrounded by one helix on one side and by five helices on the other side [1]. It contains an exposed Walker A loop in an unexpected helix-loop-helix motif (in other proteins, Walker A motifs generally adopt a P loop conformation as part of a strand-loop-helix motif embedded in a conserved topology of alternating helices and (parallel) beta strands)[1].

A 4'-phosphopantetheine prosthetic group is attached through a serine. This prosthetic group acts as a a 'swinging arm' for the attachment of activated fatty acid and amino-acid groups. This domain forms a four helix bundle. This family includes members not included in Prosite. The inclusion of these members is supported by sequence analysis and functional evidence. The related domain of Swiss:P19828 has the attachment serine replaced by an alanine.	Domain

It has been suggested that the kicB gene encodes a killing factor and the kicA gene codes for a protein that suppresses the killing function of the kicB gene product [1]. It was also demonstrated that KicA and KicB can function as a post-segregational killing system, when the genes are transferred from the E. coli chromosome onto a plasmid [1].	Domain
