A	PF14527	WhiA LAGLIDADG-like domain (LAGLIDADG_WhiA)	WhiA LAGLIDADG-like domain	This domain is found within the sporulation regulator WhiA. It is a LAGLIDADG superfamily like domain [1-2].	Domain
A	PF10298	WhiA N-terminal LAGLIDADG-like domain (WhiA_N)	WhiA N-terminal LAGLIDADG-like domain	This domain is found at the N terminal of sporulation factor WhiA. This domain is related to the LAGLIDADG Homing endonuclease domain while the C terminal domain of WhiA is predicted to be a DNA binding helix-turn-helix domain [2].	Domain
A	PF02650	WhiA C-terminal HTH domain (HTH_WhiA)	WhiA C-terminal HTH domain	This domain is found at the C-terminus of the sporulation regulator WhiA.
