Extended Data Fig. 8: Simulated outward-facing (OF) conformations of CydDC.
From: Dissecting the conformational complexity and mechanism of a bacterial heme transporter
(a) Closeup views show residues involved in heme binding. Surface model cross-sections illustrate the changing shape and size of the internal cavity in different conformational states. Surface model side views highlight the change in overall shape of the TMH region in different conformational states. (b) Closeup side views show changing orientations of TMs and heme-binding residues during conformational transitions of the predicted outward-facing states. Heme is shown as purple ball-and-stick model. ELD and TM4D are shown as tubes.
