Upgrade of Data Acquisition and Processing Systems for two High Resolution and One ESI Mass Spectrometers

这份来自化学研究仪器和设施项目的合同将帮助德州农工大学化学系的教员升级两台高分辨率质谱仪和一台ESI质谱仪的数据采集和处理系统。质谱仪将支持以下研究项目：合成肽的生成、组合肽库的筛选、合成模拟物的表征、模拟含有金属活性位点的酶的有机金属化合物的合成、含半胱氨酸的蛋白质和肽的烷基酚选择性烷基化、复杂天然产物的合成、生物修复蛋白的表征、金属配体络合。以及通过基因工程合成维生素B12质谱（MS）是一种用于探测内部结构细节和获得大量有机、生物有机和有机金属分子的分子组成的技术。电喷雾技术的加入将质谱的范围扩展到蛋白质和核酸分子量，远远超出任何其他技术。电喷雾电离结合高分辨率提供了质谱分析的最新技术。它为化学家提供了表征化合物的最有力的工具之一。在质谱法中获得这种能力对于化学许多领域的前沿研究的进行是必不可少的。

This award from the Chemistry Research Instrumentation and Facilities Program will assist faculty in the Department of Chemistry at Texas A&M University to upgrade the Data Acquisition and Processing Systems for two High Resolution and one ESI Mass Spectrometers. The mass spectrometers will support research projects focused on the generation of synthetic peptides, screening of combinatorial peptide libraries, characterization of synthetic mimics for beta sheet initiation, synthesis of organometallics to mimic enzyme containing metal active sites, selective alkylation of cysteine containing proteins and peptides by alkylphenols, synthesis of complex natural products, characterization of bioremediation proteins, metal-ligand complexation, and genetically engineered synthesis of vitamin B12.Mass spectrometry (MS) is a technique used to probe intimate structural details and to obtain the molecular compositions of a vast array of organic, bioorganic, and organometallic molecules. The addition of the technique of electrospray extends the range of MS to protein and nucleic acid molecular weights far beyond any other technique. The use of electrospray ionization in combination with high resolution provides the latest technique available in mass spectrometry. It affords the chemist one of the most powerful tools available for the characterization of compounds. The acquisition of this capability in mass spectrometry is essential for the prosecution of frontier research in many fields of chemistry.
