S1R3X_000037	COG0338	D12 class N6 adenine-specific DNA methyltransferase
S1R3X_000039	COG4653	Phage capsid family
S1R3X_000057	COG0464	growth
S1R3X_000070	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
S1R3X_000084	COG0258	In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity
S1R3X_000084	COG0749	In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity
