Figure 3. GDP release using stopped-flow and mant-GDP.
Dissociation of mant-GDP from (A) wild type and (B–G) mutant EcNFeoB proteins. The off-rate constant (koff) was determined directly from the single exponential function of the data (see Table 1). Final koff values are the average of three or more stopped-flow experiments with each experiment consisting of five or more replicates.
