Figure 1.
Figure 1. A, Molecular structure of ND1 strand swapped dimer. Molecules A and B of ND1 are colored green and cyan, respectively. The signal sequence segment of Mol B is colored red. B, The N-terminal domain of full length EMMPRIN (PDB ID 3B5H) is overlaid on Mol A and shown in gold. The residues of 58-65 are colored blue in panels A and B. For the un-swapped ND1 of 3B5H, this segment was replaced with the same segment ofthe current ND1 structure. The domain swap hinge P[91]EP[93] is colored magenta on the dimer and unswapped monomer. C, A schematic of -strand swapping of ND1.
Figure 3.
Figure 3. SEC-SLS of elution profiles of ND1 at pH 7.5 and 3.5. The ND1 protein was injected at 1.0 mg/mL onto Superdex-75 in PBS pH 7.5 or in 20 mM sodium citrate pH 3.5, 100 mM NaCl. Results show an average MW 13-16 kDa at pH 7.5 and 11 kDa at pH 3.5 based on static light scattering (SLS). The estimated molecular mass (g/mol) and protein concentration (RI, refractive index in volts) are labeled on the left and right axes, respectively.
