Fig. 4: PE lipid binding in Wzm-WztMabs in nanodiscs.
From: Structural basis of lipid-linked galactan export by the mycobacterial ABC transporter Wzm-Wzt
a Surface representation of a single Wzm-WztMabs protomer (apo structure in nanodiscs) featuring non-proteinaceous cryo-EM density (yellow, contoured at 4.7σ) corresponding to a phospholipid. b A PE lipid (sticks) modeled into the cryo-EM density (yellow, contoured at 4.7σ). Structural context of the PE lipid binding site (orange sticks) with contacting residues represented as sticks shown for the first (c) and the second (d) Wzm-WztMabs protomer.
