Fig. 3From: The binding affinity of PTPN13’s tandem PDZ2/3 domain is allosterically modulatedSuperposition of selected regions of 2D 1H-15N-HSQC NMR spectra of PDZ2, PDZ3, and PDZ2/3. The selected regions highlight congruent NMR resonances of the apo-single domains PDZ2 (red) and PDZ3 (green) as well as the PDZ2/3 tandem domain (black)Back to article page
