Figure S1. Concentration dependence of E2–Ub discharge assays.
(A, C, E) E2–UbAtto discharge assays with increasing concentrations of class VI RING domains. Assays were carried out with 4 μM of either TRIM25 or TRIM32 as a positive control, and up to 100 μM of either TRIM28 RING, TRIM24 RING, or TRIM33 RING as indicated. Reactions were monitored over 15 min. (B, D, F) Quantification of discharge assays: the loss of E2–UbAtto is plotted as the average of experimental duplicates.
