HIGH RESOLUTION SPECTROSCOPIC STUDIES IN AMRIS

该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子项目和研究者（PI）可能从另一个NIH来源获得主要资金，因此可以在其他CRISP条目中表示。所列机构为中心，不一定是研究者所在机构。使用更传统的光谱学在500，600和750 MHz仪器上进行各种光谱学研究，但利用AMRIS相关教师和工作人员的专业知识，上面只列出了相关的AMRIS相关MR教师和工作人员。这些措施包括：研究了来自酿酒酵母的天冬氨酸蛋白酶抑制剂IA 3（显示在溶液中本质上是非结构化的;确定了来自果蝇的动力蛋白轻链LC 8的pH诱导单体的溶液结构;确定了羊毛硫抗生素Mutacin 1140的结构和动力学;从Lec 1哺乳动物和Tn 5昆虫细胞表达、纯化和表征了禽类Thy 1;黑皮质素四肽Ac-His-DPhe-Arg-Trp-NH 2在小鼠黑皮质素受体上的结构-活性关系的测定;以及脂族、环状和芳族N-末端“封端”的His-D-Phe-Arg-Trp-NH 2四肽在黑皮质素受体上的表征。预计这些研究的各个方面将利用本资源中开发的微弹簧圈和HTS技术，当它们成熟时，将成为合作项目。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. A variety of spectroscopy studies are performed on the 500, 600 and 750 MHz instruments using more conventional spectroscopy, but drawing upon the expertise of the AMRIS associated faculty and staff ¿ the relevant AMRIS associated MR faculty and staff only are listed above. These include; studies of IA3, an aspartic proteinase inhibitor from Saccharomyces cerevisiae (shown to be intrinsically unstructured in solution; determination of the solution structure of the pH-induced monomer of dynein light chain LC8 from Drosophila; determination of the structure and dynamics of the Lantibiotic Mutacin 1140; expression, purification, and characterization of avian Thy1 from Lec1 mammalian and Tn5 insect cells; determination of the structure-activity relationships of the melanocortin tetrapeptide Ac-His-DPhe-Arg-Trp-NH2 at the mouse melanocortin receptors; and characterization of aliphatic, cyclic, and aromatic N-terminally "capped" His-D-Phe-Arg-Trp-NH2 tetrapeptides at the melanocortin receptors. It is anticipated that aspects of these studies will make use of the microcoil and HTS technologies developed in this Resource when they become mature, beoming collaborative projects.
