Like E.coli eukaryotic cells also contain chaperonin, which of the following in eukaryotic chapronin is incorrect?

#Unit 1. Molecules and their Interaction Relevant to Biology

  1. Eukaryotic cells contain the chaperonin TRiC, with double rings of eight nonidentical subunits

  2. TRiC proteins contain an additional segment that acts as a built-in lid, so the complex encloses a polypeptide chain and mediates protein folding without the assistance of a GroES-like cochaperone

  3. TRiC chaperonin resembles a GroES subunit, Like its bacterial TRiC operates in an ATP-dependent fashion

  4. Around 10% of eukaryotic proteins transiently interact with TRiC
