title: Crystallization and preliminary crystallographic data of 2-enoyl-CoA hydratase 2 domain of Candida tropicalis peroxisomal multifunctional enzyme type 2.
abstract: In yeast, the second and the third reaction of the fatty-acid beta-oxidation spiral are catalysed by peroxisomal multifunctional enzyme type 2 (Mfe2p/Fox2p). This protein has two (3R)-hydroxyacyl-CoA dehydrogenase domains and a C-terminal 2-enoyl-CoA hydratase 2 domain. Here, the purification, crystallization and X-ray diffraction analysis of the hydratase 2 domain [CtMfe2p(dh(a+b)Delta)] from Candida tropicalis Mfe2p is reported. CtMfe2p(dh(a+b)Delta) was overexpressed as an enzymatically active recombinant protein and crystallized by the hanging-drop vapour-diffusion method. The crystals belong to space group C2, with unit-cell parameters a = 178.57, b = 60.46, c = 130.85 A, beta = 94.48 degrees. Selenomethionine-labelled protein was used for a multi-wavelength anomalous dispersion (MAD) experiment. A three-wavelength data set suitable for MAD phasing was collected to 2.25 A resolution using synchrotron radiation.
