Figure 5
ATP–PPi exchange assay of various MtMetRS mutants. (a) Hydrogen bonds between the CP and catalytic domains are shown by dashed lines; the bond lengths are indicated. A histogram presentation of the ATP–PPi exchange activities of a collection of mutants. The catalytic activities of the mutants are expressed as the percentage relative activity compared with wild-type MtMetRS. The result represents triplicate independent measurements with error bars from calculated standard deviations.
