Crystallization and preliminary X-ray diffraction analysis of the Cmr2-Cmr3 subcomplex in the CRISPR-Cas RNA-silencing effector complex

The Cmr2-Cmr3 subcomplex from P. furiosus was co-crystallized with 3'-AMP. X-ray diffraction data for the crystals were collected to 2.6 Å resolution using a synchrotron-radiation source.
