RT   "Identification, characterization, and DNA sequence of a functional
RT   'double' groES-like chaperonin from chloroplasts of higher plants.";
RL   Proc. Natl. Acad. Sci. U.S.A. 89:8696-8700(1992).
CC   -!- FUNCTION: Seems to function only as a co-chaperone, along with cpn60,
CC       and in certain cases is essential for the discharge of biologically
CC       active proteins from cpn60.
CC   -!- SUBUNIT: Forms stable complexes with CPN60 in the presence of ATP.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast.
CC   -!- SIMILARITY: Belongs to the GroES chaperonin family. {ECO:0000305}.
