Fig. 2From: Probing contacts of inhibitor locked in transition states in the catalytic triad of DENV2 type serine protease and its mutants by 1H, 19F and 15 N NMR spectroscopy1H-15N TROSY spectra of15N labeled NS3pro, unlabeled NS2B with inhibitors (I, II). Superposition of the 1H-15N TROSY spectra of 15N labeled NS3pro, unlabeled NS2B with boronic acid (I) and tfk (II) inhibitors are shown in blue and red, respectively. The cross peaks of amino acids with the largest CSP are connected by arrows and marked according to the residue number in sequenceBack to article page
