Hard-to-identify Space Group: Finding The Best Among The Rest

This dataset was recorded from a crystal grown from a preparation of trypsin with a tight-binding protein inhibitor (low nanomolar K_d). MR was successful from data processed as P4₃, whereas the C2 data did not yield any MR solution despite having markedly superior statistics. Interestingly, the MR solution from the P4₃ dataset indicated trypsin was absent (surprising in light of the favorable binding). The question is, what is the true space group of the data?

Useful Information

Data kindly provided by: Dr. Alexander Wlodawer, Head of Protein Structure Section within Center for Cancer Research, National Cancer Institute.
Sample: crystal of trypsin inhibitor grown in the presence of trypsin (solved structure indicates no trypsin is present)
Beamline where data were collected:
Wavelength:
Detector:
Oscillation angle:
Exposure:
Distance:
Image file format:
Protein sequence in FASTA format

Two options to download the data:

Option 1 (easiest):

Use 'rsync' (linux/UNIX command) to download the compressed image files as a compressed tarball (command is in between quotes and should only be one line):

"rsync -azv anonymous@bl831.als.lbl.gov:pub/ACA2014/Alex.Wlodawer/ ."

and you will be prompted to enter 'lysozyme'.

Option 2:

Use Wget to download the 'zhoudo_argonne_Nov8th2013>BbKI_p10.tbz' file (try this if you have a Windows OS).
