Hi everyone,
I hope you are all having a wonderful week. I would like to invite you to the next International EPR society virtual seminar, which will occur on Wednesday, November 1st. Andreas Meyer from the Max Planck Institute in Göttingen will present his work on:
Developing Electron Nuclear Double Resonance Methods to Investigate Radical Enzymes and Nucleic Acids
Abstract: ENDOR probes transitions of nuclear spins coupled to nearby unpaired electron spins. This presentation is focused on 19F and 17O nuclei. 19F nuclei can be regarded as nuclear analogue of nitroxide spin labels to perform distance measurements in a distance range of ca. 0.7 – 1.5 nm. In recent months, we have worked to implement this approach at the widespread Q-band EPR set-up (1.2 T), which offers advantages in terms of sensitivity and resolution compared to the 3.4 T set-up used in most 19F ENDOR studies. The ubiquity of oxygen in biological samples renders 17O a valuable target for ENDOR studies. However, any measurement with 17O is complicated by the occurrence of quadrupole interactions, a low gyromagnetic ratio and low natural abundances. Despite this, we could detect ENDOR signatures of 17O nuclei at ca. 0.5 nm distance to the paramagnetic center, i.e. in its 2nd coordination sphere.
