Figure 4 S. cerevisiae ALAD Pb edge (PX 9.5 MAD [1]
data) anomalous difference Patterson at 3.0 Å resolution, u = ½
Harker section. The site marked by a cross was tried in a
superposition function in VECSUM but failed to bring back other
sites. It produced poor phasing statistics in MLPHARE. From the
isomorphous replacement processing of the PX 9.6 data from this
crystal against the isomorphous Hg co-crystal the site
corresponds to one of the Pb sites. The major axial peak at the
right corresponds to peaks in that processing found to have
arisen from cross vectors between the two lead sites. The map is
contoured at 94% r.m.s.
