RT   coli and Salmonella typhimurium.";
RL   J. Bacteriol. 178:293-297(1996).
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. {ECO:0000250}.
CC   -!- SUBUNIT: Heterodimer of an alpha and a beta chain.
CC   -!- SIMILARITY: Belongs to the bacterial histone-like protein family.
CC       {ECO:0000305}.
