Figure 4

(a,b) Time course of cleavage processing of Lys63-Ub4 (a) and Lys48-Ub4 (b) by 160 nM PLpro-Ubl2 and PLpro-∆Ubl2. Samples were quenched with sample buffer at the indicated time points and products were analyzed by SDS-PAGE. The negative control (time point ‘0’) was incubated without addition of enzyme.
