3.A.1.201.35 P-glycoprotein, Pgp, ABCB1, of 1241 aas and 12 TMSs with a domain order MCMC. Exports geraniol and other monoterpenes. Demissie et al. 2018 reported two structures of this homodimeric P-glycoprotein: an
outward-facing conformational state with bound nucleotide and an
inward-facing apo state, at resolutions of 1.9 Å and 3.0 Å,
respectively. Features that could be clearly visualized include ATP binding with octahedral coordination of Mg2+;
an inner chamber that significantly changes in volume with the aid of
tight connections among transmembrane helices (TMSs) 1, 3, and 6; a
glutamate-arginine interaction that stabilizes the outward-facing
conformation; and extensive interactions between TMS1 and TMS3, a property
that distinguishes multidrug transporters from floppases. These
structural elements were proposed to participate in the mechanism of the
transporter (Demissie et al. 2018).
