Differentiation of the binding of two ligands to a tetrameric protein with a single symmetric active site by 19F NMR
Differentiation of the binding of two ligands to a tetrameric protein with a single symmetric active site by 19F NMR
Abstract
R67 dihydrofolate reductase (R67 DHFR) is a plasmid-encoded enzyme that confers resistance to the antibacterial drug trimethoprim. R67 DHFR is a tetramer with a single active site that is unusual as both cofactor and substrate are recognized by symmetry-related residues. Such promiscuity has limited our previous efforts to differentiate ligand binding by NMR. To address this problem, we incorporated fluorine at positions 4, 5, 6, or 7 of the indole rings of...
