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.
CC   -!- SUBUNIT: Homodimer.
CC   -!- SIMILARITY: Belongs to the bacterial histone-like protein family.
CC       {ECO:0000305}.
