A, B	PF00239	Resolvase, N terminal domain (Resolvase)	Resolvase, N terminal domain	The N-terminal domain of the resolvase family (this family) contains the active site and the dimer interface. The extended arm at the C-terminus of this domain connects to the C-terminal helix-turn-helix domain of resolvase - see Pfam:PF02796.	Domain
