    • 2 at pH 7.6, and 2q at a concentration of 3 mM. Diffraction data were collected to a resolution of 2.3 Å on beamline 14IDB at the Advanced Photon Source at Argonne National Laboratory. This crystal structure has been deposited in the Protein Databank (www.rcsb.org) with entry code 3BSA. Full details of structure determination are given in the PDB entry.
