Climate is a critical factor affecting forest ecosystems and their capacity to produce goods and services. Effects of climate change on forests depend on ecosystem-specific factors including dimensions of climate (temperature, precipitation, drought, wind etc.). Available information is not sufficient to support a quantitative assessment of the ecological,(More)
The intramolecular conformation of puromycin, a broad spectrum antibiotic, in solution has been investigated by proton magnetic resonance (PMR) spectroscopy. A comparison of the proton chemical shift and proton-proton coupling constant data of puromycin with puromycin aminonucleoside suggests that puromycin in solution exists as an equilibrium blend of(More)
The self-association of puromycin has been studied using proton magnetic resonance spectroscopy. The concentration, temperature and pH dependence studies of the proton chemical shifts of the adenine protons indicate that puromycin in aqueous solution at pD 7.4 self associates predominantly through adenine-adenine interaction. At this pD, the amino group of(More)
