S-Ribosylhomocysteinase (LuxS) encoded by theluxSgene fromStreptococcus mutansplays a crucial role in the quorum-sensing system. LuxS was solubly expressed inEscherichia coliwith high yield. The purity of the purified target protein, which was identified by SDS–PAGE and MALDI–TOF MS analysis, was >95%. The protein was crystallized using the hanging-drop vapour-diffusion method with PEG 3350 as the primary precipitant. X-ray diffraction data were collected at Beijing Synchrotron Radiation Facility (BSRF). Diffraction by the crystal extended to 2.4 Å resolution and the crystal belonged to space groupC2221, with unit-cell parametersa= 55.3,b= 148.7,c= 82.8 Å.
