doi: 10.1101/2025.09.26.678755
Figure Lengend Snippet: a Schematic illustration of the catalytic mechanisms employed by major E3 ligase families: RING, HECT, and RBR. Acceptor lysine (on E3 or on substrate) is shown in orange. b Schematic showing the experimental workflow of the E2 discharge assay using free amino acids. c E2 discharge assay using UbcH8∼ISG15 in the presence of various amino acids (50 mM) d E2 discharge assay using UbcH8∼ISG15 in the presence of increasing concentrations of L-lys as indicated. e E2 discharge assay using UbcH7∼Ub in the presence of various amino acids (50 mM f E2 discharge assay using UbcH5A∼Ub in the presence of various amino acids (50 mM)
