Interaction between the C2 domain and the catalytic domain and its influence on PLDα1 activity. a Influence of C2 domain deletion mutation (PLD-ΔC2) and interaction residue mutations on PLDα1 activity. Results are means ± SD, n = 3. b Surface view showing the interaction between C2 domain and catalytic domain. Color codes are the same as Fig. 3b. c, d Zoom-in views of the interactions. Residues involved in the interaction are shown with sticks
