Crystallization and preliminary X-ray diffraction analysis of AntE, a crotonyl-CoA carboxylase/reductase from Streptomyces sp. NRRL 2288.

ABSTRACT: AntE from Streptomyces sp. NRRL 2288 is a crotonyl-CoA carboxylase/reductase that catalyzes the reductive carboxylation of various α,β-unsaturated acyl-CoAs to provide the building block at the C7 position for antimycin A biosynthesis. Recombinant AntE expressed in Escherichia coli was crystallized by the sitting-drop vapour-diffusion method. The crystals belonged to space group I222 or I2₁2₁2₁, with unit-cell parameters a=76.4, b=96.7, c=129.6 Å, α=β=γ=90.0°. A diffraction data set was collected at the KEK Photon Factory to 2.29 Å resolution.
