This is a domain found in polyvalent proteins of conjugative element or often in the neighbourhood of one [2]. The KfrB domain has been speculated to play a role in discrimination of self from non-self in plasmid conjugation systems [2]. This domain has been described as having an OB-fold. Additionally in some proteins it has a four stranded beta sheet elaboration to the N-terminus that packs against the side of the OB barrel that is not included in this entry. The KfrB domain is also found at the C-terminus of some zeta toxin proteins [3].
