Other Details IMAGE RECONSTRUCTION INCLUDING CONTRAST TRANSFER CORRECTION, WAS DONE AS DESCRIBED IN T.S.Baker & R.H.Cheng, J.Struct.Biol. 116, 120-130 (1996) and J.F.Conway & A.C.Steven, J.Struct.Biol. 128, 106 (1999). Nine focal pairs were analyzed, yielding 2939 particles, of which 981 were included in the final map. This map was calculated to 12 Angstroms, its resolution as assessed by Fourier Ring Correlation (cutoff 2 sigma), as calculated between reprojections of two maps from half data sets.
