PBC2_052	COG3201	nicotinamide mononucleotide transporter
PBC2_069	COG3091	SprT-like family
PBC2_076	COG4974	Belongs to the 'phage' integrase family
PBC2_082	COG3583	domain protein
PBC2_082	COG3584	3D domain protein
PBC2_083	COG0125	Phosphorylation of dTMP to form dTDP in both de novo and salvage pathways of dTTP synthesis
PBC2_090	COG0608	single-stranded DNA 5'-3' exodeoxyribonuclease activity
PBC2_102	COG0322	excinuclease ABC activity
PBC2_125	COG0187	DNA topoisomerase II activity
PBC2_126	COG0188	A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner
PBC2_130	COG1780	Probably involved in ribonucleotide reductase function
PBC2_133	COG0209	Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides
PBC2_134	COG0208	Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides
PBC2_156	COG1404	Belongs to the peptidase S8 family
PBC2_160	COG0740	serine-type endopeptidase activity
PBC2_166	COG0462	Involved in the biosynthesis of the central metabolite phospho-alpha-D-ribosyl-1-pyrophosphate (PRPP) via the transfer of pyrophosphoryl group from ATP to 1-hydroxyl of ribose-5-phosphate (Rib-5-P)
PBC2_184	COG1435	thymidine kinase activity
PBC2_186	COG0587	DNA-directed DNA polymerase activity
PBC2_188	COG0817	Nuclease that resolves Holliday junction intermediates in genetic recombination. Cleaves the cruciform structure in supercoiled DNA by nicking to strands with the same polarity at sites symmetrically opposed at the junction in the homologous arms and leaves a 5'-terminal phosphate and a 3'-terminal hydroxyl group
PBC2_197	COG5632	N-Acetylmuramoyl-L-alanine amidase
PBC2_197	COG3409	Peptidoglycan-binding domain 1 protein
PBC2_197	COG1388	LysM domain
PBC2_204	COG2433	Pfam Transposase IS66
PBC2_206	COG0739	heme binding
PBC2_206	COG0741	lytic transglycosylase activity
PBC2_206	COG1196	nuclear chromosome segregation
PBC2_208	COG1196	nuclear chromosome segregation
PBC2_208	COG0741	lytic transglycosylase activity
PBC2_208	COG0739	heme binding
PBC2_209	COG4973	Belongs to the 'phage' integrase family. XerC subfamily
PBC2_241	COG0582	viral genome integration into host DNA
PBC2_245	COG0739	heme binding
PBC2_251	COG0507	A helicase nuclease that prepares dsDNA breaks (DSB) for recombinational DNA repair. Binds to DSBs and unwinds DNA via a highly rapid and processive ATP-dependent bidirectional helicase activity. Unwinds dsDNA until it encounters a Chi (crossover hotspot instigator) sequence from the 3' direction. Cuts ssDNA a few nucleotides 3' to the Chi site. The properties and activities of the enzyme are changed at Chi. The Chi-altered holoenzyme produces a long 3'-ssDNA overhang and facilitates RecA-binding to the ssDNA for homologous DNA recombination and repair. Holoenzyme degrades any linearized DNA that is unable to undergo homologous recombination. In the holoenzyme this subunit has ssDNA-dependent ATPase and 5'-3' helicase activity. When added to pre-assembled RecBC greatly stimulates nuclease activity and augments holoenzyme processivity. Negatively regulates the RecA-loading ability of RecBCD
