UbB stimulates cIAP1R-catalyzed Ub transfer. A, nonreduced autoradiograms of lysine discharge reactions showing the disappearance of UbcH5B variant∼32P-Ub over time in the presence and absence of UbΔGG (300 μm) catalyzed by cIAP1R. B, nonreduced SDS-PAGE showing the cIAP1R-mediated discharge of fluorescently labeled UbcH5B∼Ub to l-lysine over time in the presence of UbΔGG (20 μm) or UbcH5B S22R,F62A,P95D–Ub (20 μm) visualized with a LI-COR Odyssey scanner (top) followed by staining with InstantBlue (bottom). *, fluorescently labeled Ub.
