FIG. 1.

Sso proteins have similar in vitro binding profiles to different lipids. (A) Representative images of binding assays. Liposomes were prepared in a 1:1 molar ratio with 34:1 PC and the lipid species listed above corresponding assays. Supernatant (S) and pellet (P) represent the components of a single assay. (B) Graph of percent protein bound for liposomes containing 0 to 70 mol% PA. Quantification was performed as described in Materials and Methods. Each data point represents a minimum of three independent assays; error bars represent standard error. PE, phosphatidylethanolamine; PS, phosphatidylserine; PI, phosphatidylinositol.
