M1M53_gp055	COG0258	In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity
M1M53_gp055	COG0749	In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity
M1M53_gp058	COG0756	dUTP diphosphatase activity
M1M53_gp061	COG0209	Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides
M1M53_gp061	COG1327	Negatively regulates transcription of bacterial ribonucleotide reductase nrd genes and operons by binding to NrdR- boxes
M1M53_gp066	COG0692	Excises uracil residues from the DNA which can arise as a result of misincorporation of dUMP residues by DNA polymerase or due to deamination of cytosine
M1M53_gp068	COG1179	involved in molybdopterin and THIamine biosynthesis family 1
