title: Crystallization and preliminary X-ray analysis of the aromatic prenyltransferase CloQ from the clorobiocin biosynthetic cluster of Streptomyces roseochromogenes.
abstract: Crystals of recombinant CloQ (subunit MW = 35 626 Da; 324 amino acids), an aromatic prenyltransferase from Streptomyces roseochromogenes, were grown by vapour diffusion. The protein crystallizes in space group I4(1)22, with unit-cell parameters a = b = 135.19, c = 98.13 A. Native data from a single crystal were recorded to a resolution of 2.2 A in-house. Preliminary analysis of these data indicated that the asymmetric unit corresponds to a monomer, giving an estimated solvent content of 60.6%. CloQ is involved in the biosynthesis of the aminocoumarin antibiotic clorobiocin, which targets the essential bacterial enzyme DNA gyrase.
