(A) ClpXP degradation of 10 μM 35S-labeled UmuD2 or UmuD′2. (B) Michaelis–Menten plot of ClpXP-mediated degradation of increasing concentrations of UmuD2 (KM = 26.4 ± 2.3 μM; Vmax = 1.2 ± 0.1 min-1·ClpX6-1). (C) Sequences of peptides that overlap the site of autocleavage between Cys-24 and Gly-25 were identified by tandem mass spectrometry after ClpXP-mediated degradation of UmuD2.
