CC   -!- FUNCTION: Histone-like DNA-binding protein which is capable of wrapping
CC       DNA to stabilize it, and thus to prevent its denaturation under extreme
CC       environmental conditions. Seems also to act as a fortuitous virulence
CC       factor in delayed sequelae by binding to heparan sulfate-proteoglycans
CC       in the extracellular matrix of target organs and acting as a nidus for
CC       in situ immune complex formation.
CC   -!- SIMILARITY: Belongs to the bacterial histone-like protein family.
CC       {ECO:0000305}.
