Michaelis-Menten Kinetics: Ubiquitin Rhodamine 110 serially diluted from 1.6 to 0.05microM was digested with 30pM UcHL3 over time. The assay was carried out in a reaction buffer of 50mM HEPES pH 7.5, 100mM NaCl, 1mM TCEP, 0.1mg/ml BSA, at 25°C. Initial velocities at each substrate concentration were plotted and fit to the Michaelis-Menten equation. Kinetic parameters were calculated at: Km= 0.69microM, Vmax = 1.29 nMs-1, kcat= 43s-1, kcat/Km= 6.16 x 107 M-1s-1.
