Figure 2: Msp1 extraction activity correlates with hydrophobic mismatch between the substrate TMD and lipid bilayer.
A) Composition and thickness of T-series liposomes.
B) PEG-maleimide labeling shows increased TMD exposure in thinner liposomes.
C) Quantification of data from B from 3 separate reconstitutions. Error bars show standard error of the mean. The amount of labeled material in the + detergent sample is defined as 100% labeling.
D) Extraction of the standard Sumo-Sec22 substrate in T-series liposomes. Msp1 shows more robust extraction activity in thinner liposomes.
E) Protease protection assay of standard Sumo-Sec22 substrate in T-series liposomes.
