The present invention relates to crystals of pyruvate dehydrogenase kinase (PDHK) wherein the PDHK protein includes PDHK-2 amino acid sequence as shown in SEQ ID NO: 2 but starting at amino acid position 16, or a homologue, fragment, variant or derivative thereof.). The invention also relates to high resolution three dimensional structures of PDHK in the presence and absence of physiological and synthetic ligands obtained by X-ray diffraction and use of the structures to identify, design or select compounds that bind to PDHK. The invention further relates to compounds identified, designed or selected using high resolution structures of PDHK. Also provided are nucleotide sequences used to obtain crystallisable PDHK protein.
本发明涉及丙酮酸脱氢酶激酶(PDHK)的晶体,其中PDHK蛋白包括SEQ ID NO:2所示但从氨基酸位置16开始的PDHK-2氨基酸序列,或其同源物、片段、变体或衍生物。)本发明还涉及通过 X 射线衍射获得的 PDHK 在生理配体和合成配体存在和不存在时的高分辨率三维结构,以及利用该结构鉴定、设计或选择与 PDHK 结合的化合物。本发明还涉及利用 PDHK 的高分辨率结构鉴定、设计或选择的化合物。本发明还提供了用于获得可结晶的 PDHK 蛋白的核苷酸序列。
