STRUCTURE OF T255E, E376G MUTANT OF HUMAN MEDIUM CHAIN ACYL-COA DEHYDROGENASE
Overview
Crystal structures of the wild type human medium-chain acyl-CoA, dehydrogenase (MCADH) and a double mutant in which its active center, base-arrangement has been altered to that of long chain acyl-CoA, dehydrogenase (LCADH), Glu376Gly/Thr255Glu, have been determined by X-ray, crystallography at 2.75 and 2.4 A resolution, respectively. The catalytic, base responsible for the alpha-proton abstraction from the thioester, substrate is Glu376 in MCADH, while that in LCADH is Glu255 (MCADH, numbering), located over 100 residues away in its primary amino acid, sequence. The structures of the mutant complexed with C8-, C12, and, C14-CoA have also been determined. The human enzyme structure is, essentially the same as that of the pig enzyme. The structure of the, mutant is unchanged upon ligand ... [(full description)]
