Fig. 4: Variations in GroEL carboxy terminus affect chaperonin function.

a Pairwise correlation matrices showing differential displacement of the indicated 13 residue carboxy-terminal peptides of the GroEL CTS variants that are shown and colour-coded as in Fig. S6. A to G indicate the subunit chains in the heptameric ring. b Serially diluted cultures of groEL conditional mutant strains, E. coli LG6 and E. coli MGM100 that are expressing the indicated groEL CTS variants, were spotted on LB agar plates. The plates were supplemented as indicated and incubated at 30 °C.
