Figure 3.

Structural representation of Q bound to sPLA₂ from docking simulations. (a) shows a cartoon representation of the sPLA₂ structure. quercetin is shown in a stick representation, and the Ca²⁺ ion is represented as a blue sphere. (b) shows the quercetin molecule and its main amino acid interactions. (c) shows a surface representation of sPLA₂ bound to a quercetin molecule (stick representation). (d) shows the dot representation of the Quercetin molecule in the bound position. Two amino acid residues (Asp49 and His48) from sPLA₂ are represented as sticks.
