An order–disorder twin crystal of L-2-haloacid dehalogenase from Sulfolobus tokodaii

L-2-Haloacid dehalogenase from S. tokodaii strain 7 has been cloned, overexpressed and purified. The dehalogenase has been crystallized and preliminary X-ray diffraction data are reported. The crystal was shown to be an order–disorder twin and the experimental data have been detwinned.
