Title Crystallization and X-ray analysis of D-threonine aldolase from Chlamydomonas reinhardtii.
Journal Acta Crystallogr F Struct Biol Commun
Abstract D-Threonine aldolase from the green alga Chlamydomonas reinhardtii (CrDTA) catalyzes the interconversion of several β-hydroxy-D-amino acids (e.g. D-threonine) and glycine plus the corresponding aldehydes. Recombinant CrDTA was overexpressed in Escherichia coli and purified to homogeneity; it was subsequently crystallized using the hanging-drop vapour-diffusion method at 295 K. Data were collected and processed at 1.85 Å resolution. Analysis of the diffraction pattern showed that the crystal belonged to space group P1, with unit-cell parameters a = 64.79, b = 74.10, c = 89.94 Å, α = 77.07, β = 69.34, γ = 71.93°. The asymmetric unit contained four molecules of CrDTA. The Matthews coefficient was calculated to be 2.12 Å3 Da-1 and the solvent content was 41.9%.
