Figure 2.

Double reciprocal plots of inverse of the bacterial PLC micellar substrate activity vs. inverse of the molar concentration of phospholipid for six different micelle dilution series each of constant composition given by $R=\frac{[\mathit{DPS}]}{[\mathit{lipid}]}$ for each of the three lipids: (a) DLPC; (b) DMPC; (c) DPPC in mixed micelles with the surfactant DPS. The series is also described by constant [S] or constant $X_{\mathit{lipid}}^{\mathit{mic}}$. The solid lines are fits to the predicted linear variation of eq. 12.
