Single crystals have been obtained of the toluene-4-monooxygenase catalytic effector protein, the SeMet-enriched protein and a truncated isoform missing ten amino acids from the N-terminus. Complete X-ray diffraction data sets have been collected and analyzed to 2.0, 3.0, and 1.96 Å resolution for the native, SeMet and truncated isoform crystals, respectively. The native and SeMet proteins crys...
