C [auth A]	PF02294	7kD DNA-binding domain (7kD_DNA_binding)	7kD DNA-binding domain	This family contains members of the hyper-thermophilic archaebacterium 7kD DNA-binding/endoribonuclease P2 family. There are five 7kD DNA-binding proteins, 7a-7e, found as monomers in the cell. Protein 7e shows the tightest DNA-binding ability.	Domain
