FIGURE 2.
pL-dependent kinetic parameters for the mutant t-I2020T-catalyzed phosphorylation. A, t-I2020T-catalzyed LRRKtide phosphorylation (panels A and B). Panel A, pH (●) and pD (○) dependences of kcat with a SKIE of 1.01. Panel B, pH (●) and pD (○) dependences of kcat/Km with a SKIE of 1.1. B, t-I2020T-catalzyed LRRKtideS phosphorylation (panels C and D). Panel C, pH (●) and pD (○) dependences of kcat with a SKIE of 0.50. Panel D, pH (●) and pD (○) dependences of kcat/Km with a SKIE of 0.61.
