Each diffraction pattern was automatically indexed, and the spot intensities
were
integrated either using a raster (for patterns recorded at specimen tilts
less than
30 degrees) or using profile fitting (for patterns recorded at specimen
tilts at or
greater than 30 degrees, which represented about 80% of the total data set).
Each
pattern was then compared to the curves recorded for wild-type
bacteriorhodopsin
in glucose at -100 degrees C [Ceska and Henderson J. Mol. Biol. 213: 539-560
(1990)], and the relative proportions of the four different twins
determined. This
exercise was carried out with all four theoretically possible orientations
of the
crystal axes relative to the previous reference curves to ensure that the
data were
merged correctly. From the initial set of 486 patterns chosen, 286 minimally
twinned diffraction patterns were selected in which the major twin
proportion was
greater than 0.8. These 286 patterns were merged using the wild-type lattice
lines
as a reference and lattice lines were fitted to the data to obtain an
initial
approximately merged set of lattice lines (merge #1) describing the
structure of
the triple mutant. The original set of 486 patterns was then merged against
the
new lattice curves to redetermine the twin proportions more accurately. The
merging parameters for each crystal were inspected carefully again, and 84
crystals
for which the major twin proportion was less than 0.70 were excluded from
the
data set. The remaining 402 substantially untwinned diffraction patterns
were
used to generate a new set of curves and the procedure repeated to create a
stable
set of lattice lines. The merged data were further improved by using an
estimate
of sigma values for each reflection, and by the inclusion of an individual
weighting factor for each diffraction pattern using procedures described by
Grigorieff
and Henderson [Ultramicroscopy 60: 295-309 (1995)]. Two cycles of this
refinement were carried out to obtain a final set of merged curves. The
curves
were sampled at 1/100 Angstroms (approximately twice the thickness of the
membrane) to obtain a set of intensities at H,K,L values so that the data
could
be further processed with standard X-ray crystallographic programs. For the
tilt angles used, the maximal possible theoretical completeness of the data
set
is ~87%. The completeness of our data is close to this limit up to 3.5
Angstroms.
The completeness drops to 77.7 % when all of the data to 3.2 Angstroms is
included.
