Abstract
Paramagnetism-assisted nuclear magnetic resonance (NMR) techniques can provide long-range structural information complemented with local information derived from chemical-shift perturbation and nuclear Overhauser effect data. Here, we address the application of paramagnetic relaxation enhancement (PRE) to detect inhibitor-induced conformational change of a drug target protein using human immunodeficiency virus type 1 reverse transcriptase (HIV-1 RT) as a model protein. Using a site-specific spin-labeled HIV-1 RT mutant with selective (13) C labeling, conformation-dependent PREs were successfully observed reflecting the stabilization of an open conformation of this enzyme caused by inhibitor binding. This study demonstrates that the paramagnetism-assisted NMR approach offers an alternative strategy in protein-based drug screening to identify allosteric inhibitors of a target protein.
