Iterative rebuilding of gene 5 protein beginning with structure 2gn5 and using structure-factor amplitudes corresponding to 1vqb. (a) Number of residues built and aligned to sequence as a function of cycle number and resolution of data used (open circles, 2.3 Å; closed circles, 2.5 Å; open squares, 2.7 Å). Gene 5 protein has 87 amino-acid residues; the refined model 1vqb contains 86. (b) R.m.s. coordinate difference between refined intermediate models and 1vqb for main-chain atoms (symbols as in a). (c) Number of residues built in 50 cycles as a function of resolution of data used. Open circles, main chain; closed circles, side chains. (d) R.m.s. coordinate difference between refined intermediate models at cycle 50 as a function of the resolution of the data used.
