CC   -!- FUNCTION: Might have a role analogous to that of eukaryotic histone
CC       proteins.
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}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAP98845.1; Type=Erroneous initiation; Evidence={ECO:0000305};
