The recently discovered bacterial twin-arginine translocation (Tat) pathway was investigated in Streptomyces lividans, a gram-positive organism with a high secretion capacity. The presence of one tatC and two hcf106 homologs in the S. lividans genome together with the several precursor proteins with a twin-arginine motif in their signal peptide suggested the presence of the twin-arginine transl...

The title compound, C(19)H(18)O(7), also known as chrysoobtusin, was isolated from Cassia tora L. (Leguminosae). The anthraquinone ring system is almost planar, the dihedral angle between the two benzene rings being 4.27 (4)°. The structure is stabilized by intra- and inter-molecular O-H⋯O and C-H⋯O hydrogen bonds, and by weak π-π stacking inter-actions along the b axis, with a centroid-centroi...

In this paper, the robust stabilization of asymptotically null-controllable linear systems via bounded controls is revisited. Based on the notion of “converging-input bounded-state” stability rather than “small-input small-state” stability, the complicated computations of perturbation bounds appeared in Sussmann et al (1994) are avoided. With the suggested method, a robust stabilizing control l...
