Crystallization and preliminary X-ray analysis of S-­ribosylhomocysteinase from Streptococcus mutans

S-Ribosylhomocysteinase (LuxS) encoded by the LuxS gene from Streptococcus mutans was solubly expressed in Escherichia coli, purified and crystallized. Diffraction by the crystal extended to 2.4 Å resolution.
