项目摘要
This subproject is one of many research subprojects utilizing the resources
provided by a Center grant funded by NIH/NCRR. Primary support for the subproject
and the subproject's principal investigator may have been provided by other sources,
including other NIH sources. The Total Cost listed for the subproject likely
represents the estimated amount of Center infrastructure utilized by the subproject,
not direct funding provided by the NCRR grant to the subproject or subproject staff.
Electron transfer dissociation (ETD) can be used to provide unique and complementary fragment ions when compared to other dissociation techniques, such as collision induced dissociation (CID). Weak side chain bonds such as are observed at phosphorylated amino acids in peptides are often lost during CID, but preserved during ETD. This makes the technique useful for the detection and analysis of posttranslational modifications in peptides and intact proteins. This project is devoted to the development and improvement of ETD for such applications.
这个子项目是许多利用资源的研究子项目之一
由NIH/NCRR资助的中心拨款提供。子项目的主要支持
而子项目的主要调查员可能是由其他来源提供的,
包括其它NIH来源。 列出的子项目总成本可能
代表子项目使用的中心基础设施的估计数量,
而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。
与其他解离技术(例如碰撞诱导解离(CID))相比,电子转移解离(ETD)可用于提供独特且互补的碎片离子。 弱侧链键,如在肽中磷酸化氨基酸处观察到的,通常在CID期间丢失,但在ETD期间保留。 这使得该技术可用于检测和分析肽和完整蛋白质中的翻译后修饰。 该项目致力于开发和改进ETD的应用。
