X-ray scattering pattern and models of subunit C from yeast V-ATPase. Top: (1) experimental SAXS curve; (2) and (3) scattering from typical ab initio GASBOR and DAMMIN models, respectively; (4) scattering from the high-resolution model of subunit C which was determined later [PDB code 1U7L; Drory et al. (2004)] calculated by the program CRYSOL (Svergun et al., 1995). The computed distance distribution function of subunit C is displayed in the insert. Bottom: ab initio low-resolution models reconstructed by DAMMIN and GASBOR (displayed as beads and dummy residues, respectively), superimposed with the crystallographic model (wire frames). Models in the bottom row are rotated counterclockwise by 90° around the y axis. |
