title: Crystallization and preliminary X-ray analysis of the O-methyltransferase NovP from the novobiocin-biosynthetic cluster of Streptomyces spheroides.
abstract: Crystals of recombinant NovP (subunit MW = 29 967 Da; 262 amino acids), an S-adenosyl-L-methionine-dependent O-methyltransferase from Streptomyces spheroides, were grown by vapour diffusion. The protein crystallized in space group P2, with unit-cell parameters a = 51.81, b = 46.04, c = 61.22 A, beta = 104.97 degrees. Native data to a maximum resolution of 1.4 A were collected from a single crystal at the synchrotron. NovP is involved in the biosynthesis of the aminocoumarin antibiotic novobiocin that targets the essential bacterial enzyme DNA gyrase.
