Fig. 6. The in vitro lipid binding assays of PAP-domains. A and C, schematic representations of the mutant residues in OsFBN2 and OsFBN4 proteins in the in vitro lipid binding assays. B and D, the in vitro lipid-binding activity assays were performed by a fluorescence lipid probe P-96 (1 mM), fatty acids with C12:0, C14:0, C16:0, C18:0, C20:0, C22:0, with each (0.5 mM) of wild type (Wt) and mutant fusion protein (Mut) of PAP domains in OsFBN2 and OsFBN4 proteins, respectively. Detection experiments were performed with three biological replicates. * and ** symbols indicated the significant difference levels of P <0.05 or P <0.01 between mutant and wild type, respectively.
