Title: Crystallization and preliminary X-ray diffraction analysis of ω-amino acid:pyruvate transaminase from Chromobacterium violaceum

Journal Article · · Acta Crystallographica. Section F

An ω-amino acid:pyruvate transaminase from C. violaceum has been purified and crystallized in two crystal forms. The structure has been solved using molecular replacement. The enzyme ω-transaminase catalyses the conversion of chiral ω-amines to ketones. The recombinant enzyme from Chromobacterium violaceum has been purified to homogeneity. The enzyme was crystallized from PEG 4000 using the microbatch method. Data were collected to 1.7 Å resolution from a crystal belonging to the triclinic space group P1, with unit-cell parameters a = 58.9, b = 61.9, c = 63.9 Å, α = 71.9, β = 87.0, γ = 74.6°. Data were also collected to 1.95 Å from a second triclinic crystal form. The structure has been solved using the molecular-replacement method.
