NMR STRUCTURE OF THE LANTIBIOTIC ACTAGARDINE, 15 STRUCTURES
Overview
The three-dimensional solution structure of the lantibiotic actagardine, was determined at high resolution by homonuclear and heteronuclear, two-dimensional and three-dimensional NMR spectroscopy in, [2H3]acetonitrile/H2O (7:3). 133 non-trivial distance and 22, torsional-angle constraints were derived from the NMR data. An ensemble of, 15 low-energy structures was calculated by distance geometry followed by, an iterative relaxation-matrix-refinement procedure. The rmsd of the, backbone coordinates with respect to the average structure was 17 pm. The, two distinct thioether ring systems 1-6 and 7-19 were even better defined, with backbone rmsd of 10 pm and 14 pm, respectively. Actagardine shows a, rigid compact globular shape based on the constraining bridging pattern, which is composed of ... [(full description)]
