Interaction of kaempferol with active sites of S. cerevisiae α-glucosidase. The binding model (a) and the hydrophilic interactive mode (b) of kaempferol in the substrate binding pocket of the crystal structure (PDB: 3A4A). The carbon atom of kaempferol is in the dark blue color, the carbon atom of protein is in the blue color, the oxygen atom is in the red color and the hydrogen atom is in the white color. The green line indicates the hydrogen bond interaction. The pink line indicates the π-π interaction.
