This study aimed to investigate the binding affinity between CGA and urease and explore the underlying molecular mechanism. Inhibition kinetics were characterized using Lineweaver\u2013Burk plots, fluorescence quenching, isothermal titration calorimetry (ITC), and surface plasmon resonance (SPR). The binding mode was elucidated using molecular docking and molecular dynamics simulations.
