项目摘要

An award is made to the University of Arizona to support the purchase of an analytical ultracentrifuge (AUC). More than 20 laboratories will use the new AUC, with research programs spanning basic biology, chemistry, materials science, and even biomedical research. As part of the research effort, 235 students, including 22 postdoctoral, 68 graduate and 145 undergraduate students will benefit from training with the state-of-the-art instrumentation. The training opportunities will be extended to collaborating schools and institutions across the Southwest. The University of Arizona is a Hispanic Serving Institution and hosts many programs supporting diversity and inclusion of under-represented groups, many of which will benefit from training with the new instrument. The AUC will also be used in the undergraduate lab courses, where students will test hypotheses they generate for structure and function of various enzymes. In addition, a “hands-on” demonstration showing the basic principles of ultracentrifugation will be developed in the outreach course for delivery at schools throughout Arizona.Research that will be facilitated by the AUC includes the investigation of a new enzyme mechanisms involving filament formation, DNA binding by viral replicative proteins, protein-protein interactions in cell signaling, and liquid droplet formation by intrinsically disordered proteins. The AUC will facilitate a range of research projects by providing rapid and accurate assessment of ligand binding affinity, stoichiometry, and when mechanisms of inhibition involve alterations of quaternary structure. Chemical labeling (and completeness of labeling) of proteins can be detected, as well as any effects on quaternary structure, solubility, and aggregation. Aggregation is a major roadblock to many structural and functional studies, and the new AUC will be used to assess protein preparation stability and aggregation. The masses and polydispersity of lipid containing nanodiscs will be analyzed to understand the effect of chain and headgroup size, structure, and chemistry on lipid packing. Materials science research will also benefit from the analysis of nanoparticles made from tungsten, molybdenum, and titanium. Results from these studies will be disseminated through peer-reviewed journals, presentations at scientific meetings, and through classes and public outreach presentations.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

向亚利桑那大学颁发了奖励，以支持购买分析性超级离心设备（AUC）。超过20个实验室将使用新的AUC，其中包括基本生物学，化学，材料科学甚至生物医学研究的研究计划。作为研究工作的一部分，235名学生，包括22名博士后，68名毕业生和145名本科生将受益于最先进的仪器的培训。培训机会将扩展到西南部的学校和机构的合作。亚利桑那大学是一家西班牙裔服务机构，主持许多支持多样性和包括代表性不足的团体的计划，其中许多将受益于新工具的培训。 AUC还将在本科实验室课程中使用，学生将测试他们为各种酶的结构和功能产生的假设。此外，还将在AUC进行的“动手”演示中，展示超速离心的基本原理，以在整个亚利桑那州的学校提供，用于在整个亚利桑那州的学校交付。研究包括对新的酶形成的新酶形成的调查，涉及蛋白质的蛋白质与蛋白质 - 蛋白质相互作用，蛋白质与液体相互作用，液态液滴蛋白与液体相互作用。 AUC将通过对配体结合亲和力，化学计量学以及抑制二次结构的抑制作用改变机制进行快速准确评估，从而促进一系列研究项目。可以检测到蛋白质的化学标记（和标记的完整性），以及对第四纪结构，溶解度和聚集的任何影响。聚集是许多结构和功能研究的主要障碍，新的AUC将用于评估蛋白质制备稳定性和聚集。将分析含有纳米散发的脂质的质量和多分散性，以了解链和头组大小，结构和化学对脂质填料的影响。材料科学研究还将受益于对钨，钼和钛制成的纳米颗粒的分析。这些研究的结果将通过经过同行评审的期刊，科学会议的演讲以及课程和公共外展演讲来传播。该奖项反映了NSF的法定任务，并通过基金会的知识分子优点和更广泛的影响审查标准，通过评估来诚实地诚实地支持。
