FDJ24_gp40	COG0258	In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity
FDJ24_gp40	COG0749	In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity
FDJ24_gp58	COG0207	Catalyzes the reductive methylation of 2'-deoxyuridine- 5'-monophosphate (dUMP) to 2'-deoxythymidine-5'-monophosphate (dTMP) while utilizing 5,10-methylenetetrahydrofolate (mTHF) as the methyl donor and reductant in the reaction, yielding dihydrofolate (DHF) as a by-product. This enzymatic reaction provides an intracellular de novo source of dTMP, an essential precursor for DNA biosynthesis
