CC   -!- FUNCTION: Might have a role in establishing the nucleoid structure of
CC       elementary bodies.
CC   -!- DEVELOPMENTAL STAGE: Specific to the EB (elementary body) form in the
CC       life cycle of chlamydiae.
CC   -!- SIMILARITY: Belongs to the histone H1/H5 family. HCT subfamily.
CC       {ECO:0000305}.
