Figure 7

(A) Initial velocity pattern of the Mat2A/Mat2B complex using assay 1. ATP was varied (30–500 μM) at several fixed l-Met concentrations (5–80 μM). Please note that the left and right graphs are representations of the same data, the difference being the substrate that is plotted on the x axis and the substrate that is held fixed at several levels as indicated. (B) SAM product inhibition of the Mat2A/Mat2B complex. ATP was varied (30–500 μM) at a fixed saturating concentration of l-Met (600 μM) and at the indicated concentrations of SAM. Symbols show experimental data, and solid lines show simultaneous fits of all data points to eq 1 in panel A and eq 4 in panel B.
