Fig. 3 in Anthocyanin 5,3 -aromatic acyltransferase from Gentiana triflora, a structural insight into biosynthesis of a blue anthocyanin

Fig. 3. Caffeoyl-CoA binding site. The backbone structures are depicted as tubes, and the amino acid residues and caffeoyl-CoA are depicted as sticks. (A) Caffeoyl group interactions. Hydrogen bonds are indicated by dashed lines. (B) Backbone movement. The backbone structures of the apo and complexed form of Gt5,3′ acyltransferase are shown in blue and gray, respectively. The backbone shifts are indicated by arrows upon caffeoyl-CoA binding. (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)
