ESR STUDY OF BACTERIAL CYTOCHROME C

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 来自罗切斯特大学化学系的Bren小组利用ACERT的X波段EPR仪器研究了一系列细菌细胞色素c（cyt c）变体。这些研究是一个正在进行的调查的功能影响的血红素辅因子的平面外扭曲的一部分。ACERT提供的连续流液氦低温恒温器对于这些实验是必不可少的，因为由于相对较短的自旋-晶格弛豫时间，在30 K以上通常观察不到细胞c的EPR谱。

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. The Bren group from the University of Rochester's Department of Chemistry utilized the X-Band EPR instrumentation at ACERT to study a series of bacterial cytochrome c (cyt c) variants. These studies were part of an on-going investigation of the functional implications of out-of-plane distortions of the heme cofactor. The continuous-flow, liquid helium cryostat available at ACERT is essential for these experiments because the EPR spectra of cyts c are typically not observed above 30 K due to a relatively short spin-lattice relaxation time.
