Figure 5.
The conformational shift of Pgp. Left: The mouse Pgp structure in the
inward-facing conformation (Li et al., 2014).
Highlighted are two residues, 511 and 1043, which are on opposite halves of Pgp.
Middle: The structure of human Pgp in the outward-facing conformation (Kim and Chen, 2018). Right: The closure of the
NBDs is shown in detail, highlighting the nearness of the residues 511 and 1043 in the
outward-facing conformation. PDB, Protein Data Bank.
