Figure 6From: Crystal structure and biophysical characterization of the nucleoside diphosphate kinase from Leishmania braziliensis Analysis of Lb NDK tryptophan fluorescence quenching. Modified Stern-Volmer plots for quenchers (A) iodide and (B) acrylamide, both at pH 4.0 (black squares) and 7.0 (red squares). Protein at 0.06 mg.mL−1 was excited at 295 nm and data collected from 300 to 450 nm.Back to article page
