Amino acid alignment of the membrane-binding domain of Ankyrin family proteins Twnenty-four ankyrin repeats (R1-R24) comprise the membrane-binding domain of ankyrin (270 kda) family proteins. Exactly 33 amino acid residues are aligned in each repeat. An exceptionally short loop is seen between R5 and R6 and there is an extra sequence between R6 and R7. Secondary structure is shown at the top. An arrow indicates the position of Cys70. Residues that interact to the membrane (Fig. 5) are highlighted in color. Conserved residues are boxed. Protein abbreviations are rank3 (rat AnkG, AF102552.1); hank3 (human AnkG, NM_001149); rank2 (rat AnkB, XM_00107608); hank2 (human AnkB, NM_001148); mank1 (mouse AnkR, NP_001104253); hank1 (human AnkR, NP_000028). 3

Secondary structures were determined from the crystal structure of ANK3 (R1-5). Cys (colored in red) situated in the linker (yellow) between the first and second repeats (green) is highlighted.

Fig. S3 Comparison of the structures of the reduced and oxidized forms of AnkG A) The crystal packing of the P2 1 2 1 2 crystal (the reduced form). Two molecules of AnkG (R1-R5) are in the asymmetric unit. B) The crystal packing of the C121 crystal (the oxidized form). An AnkG (R1-R5) dimer is in the asymmetric unit. C) Superposition of the reduced and oxidized structures (overall Cα-r.m.s.d. of 0.732 Å). Regarding the finger loop of R2, the Ca 2+ binding pocket, there is little difference between reduced and oxidized structures (Cα-r.m.s.d. of 0.601 Å). The structure of the R2 finger loop is also close to those of AnkB (Cα-r.m.s.d.s of 0.497 Å; 8

AnkG-oxidized vs. AnkB-Nav, 0.375 Å; AnkG-oxidized vs. AnkB-AS). D) Superposition of each monomer in the crystal form of the oxidized dimer (overall Cα- r.m.s.d. of 1.753 Å). 9

Fig. S4 A) Structure (stick models) and 2Fo-Fc maps (1.5 σ) around Cys70. B) AnkG s ability to form a disulfide bond in solution was examined. Molecular stoichiometry determined using size exclusion chromatography monitored at 280 nm. The dimer population increased progressively when the protein sample was left in mildly oxidizing buffer (100 μm H 2 O 2 ), and reduction of the protein using 5mM DTT led to recovery of the monomeric form. The elution volume V E was corrected for the void elution volume by subtracting the volume of blue dextran (V 0 ). 10

Fig. S5 Data in each trajectory of the MD simulation for the membrane association of AnkG A) Membrane contacts (red) and insertions (black) in the simulation of palmitoylated AnkG (Fig. 3). Events in all 100 trajectories were counted in chronological order. B,C) Membrane contact events by the non-palmitoylated AnkG (Fig. 4A) (B) and the AnkG dimer (Fig. 4B) (C). 11

Fig S6 Correlations between contact probability and surface ratio. Surface area ratios were calculated for the AnkG crystal structure and for the coarse-grained model. Data were plotted over the contact probability of the palmitoylated AnkG (Fig. 3C). Distributions nicely overlapped with each other, suggesting that AnkG contacted the membrane with its surface randomly before anchoring. 12
