Figure 3

The equatorial domains in three interacting GroEL subunits.
Five regions (I-V) from the HDX comparison of GroEL-ATPγS vs. apo GroEL are colored as in Fig. 1. Two subunits in the top GroEL ring and one in the bottom ring are chosen to represent the inter-subunit and inter-ring interactions (viewed from the outside of the cylinder). Representative peptides for the regions are shown in the inset table.
