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]. [1]. 10986251.

This domain is found at the C-terminus of the sporulation regulator WhiA. It is predicted to form a DNA-binding helix-turn-helix structure [2]. The WhiA protein also contains two N-terminal domains that are distant homologues of LAGLIDADG homing endonucleases [2]. [1]. 10986251.

DNA-binding protein WhiA has been reported to be involved in cell division and chromosome segregation; while WhiA binds DNA, it may not function as a transcriptional regulator

This family describes a DNA-binding protein widely conserved in Gram-positive bacteria, and occasionally occurring elsewhere, such as in Thermotoga. It is associated with cell division, and in sporulating organisms with sporulation.
