>TIGR02773 addB_Gpos ATP-dependent nuclease subunit B; InterPro: IPR014140 DNA repair is accomplished by several different systems in prokaryotes. Recombinational repair of double-stranded DNA breaks involves the RecBCD pathway in some lineages, and AddAB (also called RexAB) in others. AddA is conserved between the firmicutes and the alphaproteobacteria, while its partner protein (RexB) is not. This entry describes the ATP-dependent nuclease subunit B (AddB/RexB) protein as found Bacillus subtilis and related species. Although the RexB protein of Streptococcus and Lactococcus is considered to be orthologous and functionally equivalent, merely named differently, all members of this protein family have a P-loop nucleotide binding motif GxxGxGK[ST] at the N-terminus, unlike RexB proteins, and a CxxCxxxxxC motif at the C-terminus, both of which may be relevant to function..
