Fig. 9. Comparison of full-length Vps4p with cryo-EM reconstructions of type II AAA proteins.
Full-length Vps4p, ClpB (EMDB ID 1243), NSF-αSNAP-SNARE (EMDB ID 1059), p97-p47 (EMDB ID 1191) and p97 (from E. M. Wilson-Kubalek) maps, all in presumably ATP-bound states, contoured at their full estimated molecular weights. The D2 rings of the type II AAA proteins face the viewer in the top row and comprise the lower rings in the bottom row.
