    Abstract:
    MitoNEET (a mammalian mitochondrial outer membrane protein) is a potential pharmacological and clinical target of the insulin-sensitizer pioglitazone. The thermophilic homologue of mitoNEET (TTHA0026) from Thermus thermophilus HB8 has been heterologously overproduced in Escherichia coli and purified as a water-soluble prototypal protein containing the mitoNEET-like [2Fe-2S] cluster. The resultant recombinant protein, named Tth-NEET0026, has been crystallized in its oxidized form by the hanging-drop vapour-diffusion method using 17%(w/v) polyethylene glycol 4000, 8.5%(v/v) 2-propanol, 15%(v/v) glycerol and 0.085 M HEPES-NaOH pH 7.2. The dark reddish crystals diffracted to 1.80 A resolution and belonged to the tetragonal space group P4(3)2(1)2, with unit-cell parameters a = 45.51, c = 84.26 A. The asymmetric unit contains one protein molecule.
