The structure and epitope mapping of the complex arginase:antibody was determined by cryo-electron microscopy. The antibody was assessed for its potency and extent of inhibition of human arginase using an assay that detects the formation of thioornithine from thioarginine. In this assay, as well as an LCMS assay, it was determined that the antibody could fully inhibit the enzymatic activity of arginase. To assess the kinetic mechanism of inhibition of the antibody, increasing fixed concentrations of antibody were tested across a range of thioarginine concentrations. The Ki for the antibody against human Arg1 was 3.3 +/- 0.3 nM (Palte et al., 2021; PMID: 34326456).
