Effects of charge mutations of ClC-0 on the MTS modification rates of Y512C mutants. (A) MTSES modification process of Y512C in the presence of WT, G352E, H401E, or K149L background. The color codes are: black, Y512C/WT; red, Y512C/G352E; green, Y512C/H401E; blue, Y512C/K149L. (B) MTSEH modification time course of the same mutants as in A. (C) Calculated rate constants of MTSES and MTSEH modifications of the mutants shown in A and B. Note that the K149L mutation significantly alters the MTSES modification rate but not the MTSEH modification rate. Color codes of different mutants in B and C are the same as that in A. (D) Rate constants of MTSES, MTSEH, and MTSEA modifications of Y512C in the presence of various amino acids at position 149 as indicated.
