The upper stem of helix 34, consisting of the base-paired sequences C1063G1064U1065 and A1191C1192G1193, is suggested to be involved in the binding of spectinomycin. In E. coli 16S rRNA, each of the three mutations at position C1192 confers resistance to spectinomycin. In chloroplast ribosomes from tobacco plants and algae, resistance is conferred by single(More)
Producing high quality forage remains a challenge due to potential protein degradation during ensiling. Ten grass species and four cereals were screened for proteolytic inhibition, polyphenol oxidase (PPO) activity, and the presence of soluble PPO substrates. In orchardgrass, ryegrass, smooth bromegrass, and meadow fescue extracts, the addition of caffeic(More)
We present a novel preparation method for the self assembly of covalently anchored phospholipid supported membranes. The surface is gold covered by cysteamine. Vesicles containing DMPC and activated DODA-Suc-NHS-lipids assembled on this surface. The whole self-assembly process is monitored conveniently by Near Infrared Surface Plasmon Resonance (NIR-SPR).(More)
The present work deals with the assembly of multilayers or rod-like polymers with hydrophobic side chains (called hairy rods) and their potential application as ultrathin polymer cushions for the build-up of self healing supported membranes on various solids (Si/SiO2-wafer, gold covered substrates). Three types of hairy rods were studied: Isopentyl(More)
