NMR Technologies for Integrating Structure, Function and Disease

INTRODUCTION TO REVISED APPLICATION The A0 grant was submitted in May 2019, before Prof. Alexander Barnes moved to ETH-Zurich and before Prof. Chad Rienstra was recruited to UW-Madison. Now Rienstra is officially a Full Professor at UW-Madison, after having negotiated major investments in the solid-state NMR (SSNMR) program at NMRFAM (new and/or moving

from Illinois) including three shielded 600 MHz magnets, one 750 MHz wide bore magnet, four spectrometers, several custom-designed magic-angle spinning (MAS) probes at 600-750 MHz, and upgrades to the 900 MHz spectrometer, which immediately have had an impact on data collection for DBP6 in late 2019 and for other

experiments in progress during early 2020. Furthermore, the National Science Foundation Mid-Scale Research Infrastructure-2 proposal on "Network for Advanced NMR", which was submitted by UW-Madison PIs (Rienstra and Henzler-Wildman) in collaboration with Jeff Hoch at UConn Health and Art Edison at U. Georgia, is in late stages of negotiation and review with

NSF. If funded, this grant would bring a 1.1 GHz dedicated SSNMR spectrometer to NMRFAM in ~2022-23. These developments have motivated several changes to this A1 application which more explicitly emphasizes the SSNMR program at NMRFAM: (1) Rienstra is now contact PI and Henzler-Wildman co-PI. (2) TR&D1 now includes sub-aims targeting development of micro-rotor packing and sample manipulation

tools to leverage recent breakthroughs in ultra-fast MAS (>100 kHz) at
