Reactive conformation
WebFeb 2, 2007 · Dimerization thus occurs only for thymine residues that are already in a reactive conformation at the instant of excitation (28, 29). Excited states of unfavorably oriented thymines are quenched before a change of conformation can occur. The extent of dimerization under steady-state irradiation thus depends on the fraction of time that a … WebFeb 12, 2024 · L718Q mutant EGFR escapes covalent inhibition by stabilizing a non-reactive conformation of the lung cancer drug osimertinib Chem Sci. 2024 Feb 12;9(10) :2740-2749. ... The results show that Gln718 affects the conformational space of the EGFR-osimertinib complex, stabilizing a conformation of acrylamide which prevents reaction with Cys797.
