locus-tag	class	description
ABP1_00029	COG3566	protein conserved in bacteria
ABP1_00043	COG2369	cell adhesion
ABP1_00046	COG3728	DNA packaging
ABP1_00052	COG2901	Activates ribosomal RNA transcription. Plays a direct role in upstream activation of rRNA promoters
ABP1_00056	COG4570	Endonuclease that resolves Holliday junction intermediates made during homologous genetic recombination and DNA repair. Exhibits sequence and structure-selective cleavage of four-way DNA junctions, where it introduces symmetrical nicks in two strands of the same polarity at the 5' side of dinucleotides. Corrects the defects in genetic recombination and DNA repair associated with inactivation of ruvAB or ruvC
