Application

Application Comment Organism
nutrition identification of 17 diet-derived constituents as inhibitors, with Kiss that vary approximately 300fold. Inhibitors bind within the active site and elucidate key enzyme-inhibitor interactions. QSAR modeling identified three structural descriptors that correlate with inhibition potency Homo sapiens

Crystallization (Commentary)

Crystallization (Comment) Organism
homology modeling and docking of inhibitors epigallocatchin and epigallocatechin gallate. Interactions include pi-stacking between the phenyl rings of epigallocatchin and residues F923 and F885 and hydrogen bonding between two phenol groups and the carboxylate group on residue E882 Homo sapiens
