DESCRIPTION (provided by applicant): The Biomolecular NMR facility at The Scripps Research Institute is one of the foremost in the United States. Scripps has made an extraordinary investment over the past two decades in building and equipping this facility but the electronics consoles on many of the spectrometers are now obsolete and need to be replaced. This proposal requests funding to replace the obsolete 1997-vintage DRX console on our most sensitive instrument, an 800 MHz spectrometer equipped with a cryogenic probe, with a state-of- the-art Avance III console. The new electronics console is expected to increase the sensitivity of the instrument by as much as 25%, provide enhanced radiofrequency generation and phase stability to improve the performance of demanding pulse experiments, and enable the implementation of new 2H relaxation and non-linear sampling experiments that simply cannot be performed with our existing instrumentation. The upgraded electronics will directly benefit the NIH-funded research programs of four major user groups (Dyson, Williamson, Wright, and W|thrich) and two minor users (Kelly and Otomo). These research programs are probing fundamental questions in structural biology and are addressing key issues related to human health and disease. The enhanced capabilities of the instrument will facilitate ongoing and future research on the underlying molecular basis of cancer, myotonic dystrophy, neurodegeneration, amyloid diseases, and infectious disease.

描述（由申请人提供）：Scripps研究所的生物分子NMR设施是美国最重要的之一。在过去的二十年中，斯克里普斯（Scripps）在建造和装备此设施方面进行了非凡的投资，但是许多光谱仪上的电子游戏机现在已经过时，需要更换。该提案要求资金替代我们最敏感的仪器上的过时的1997年老式DRX控制台，即配备有低温探针的800 MHz光谱仪，并配备了Art-Art Art-Art Avance III控制台。预计新的电子控制台将使仪器的敏感性提高多达25％，提供增强的射频产生和相位稳定性，以提高苛刻的脉冲实验的性能，并实现新的2H放松和非线性采样实验，这些实验根本无法通过我们现有的仪器进行。升级的电子产品将直接受益于NIH资助的四个主要用户组（Dyson，Williamson，Wright和W | Thrich）和两个次要用户（Kelly和Otomo）的研究计划。这些研究计划正在探测结构生物学的基本问题，并正在解决与人类健康和疾病有关的关键问题。该仪器的功能增强将促进有关癌症，肌发育症，神经变性，淀粉样蛋白疾病和传染病的基础分子基础的持续和未来研究。
