Mechanisms of Protein Sequence Divergence and Incompatibility
Figure 3
Growth rates and catalytic efficiencies of the evolved variants.
(a) Growth rates of the evolved serine 219 hPGK variants and of their lysine 219 counterparts. (b) kcat/KM values of the same variants (log scale). Error bars represent S.D of 8 measurements. Each double headed dashed arrow connects a 219 serine variant with its 219 lysine counterpart.
