title: Crystallization and preliminary X-ray analysis of AbsC, a novel regulator of antibiotic production in Streptomyces coelicolor.
abstract: Crystals of recombinant AbsC (subunit MW = 18 313 Da; 158 amino acids), a novel regulator of antibiotic production from Streptomyces coelicolor, were grown by vapour diffusion. The protein crystallizes in space group P2(1)2(1)2(1), with unit-cell parameters a = 43.53, b = 121.30, c = 143.75 A. Native data to a resolution of 2.25 A were recorded at station PX 14.1 (Daresbury) from a single crystal. Preliminary analysis of these data suggests that the asymmetric unit contains four copies of the AbsC monomer, giving an estimated solvent content of 47.0%. AbsC belongs to the MarR family of proteins that mediate ligand-responsive transcriptional control.
