LIPOYL DOMAIN OF PYRUVATE DEHYDROGENASE COMPLEX, NMR, 29 STRUCTURES
OverviewOverview
The three-dimensional structure of the N-terminal lipoyl domain of the, acetyltransferase component of the pyruvate dehydrogenase complex from, Azotobacter vinelandii has been determined using heteronuclear, multidimensional NMR spectroscopy and dynamical simulated annealing. The, structure is compared with the solution structure of the lipoyl domain of, the A. vinelandii 2-oxoglutarate dehydrogenase complex. The overall fold, of the two structures, described as a beta-barrel-sandwich hybrid, is very, similar. This agrees well with the high similarity of NMR-derived, parameters, e.g. chemical shifts, between the two lipoyl domains. The main, structural differences between the two lipoyl domains occur in a, solvent-exposed loop close in space to the lipoylation site. Despite their, high ... [(full description)]
