locus-tag	class	description
Elanor_BL40011	COG0209	Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides
Elanor_BL40011	COG1327	Negatively regulates transcription of bacterial ribonucleotide reductase nrd genes and operons by binding to NrdR- boxes
Elanor_BL40059	COG0262	Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis
Elanor_BL40067	COG0258	In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity
Elanor_BL40067	COG0749	In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity
