Figure 7From: PepT1 mRNA expression levels in sea bream (Sparus aurata) fed different plant protein sources The sites of binding for organic acids and metals in the PepT1 of D.labrax , as predicted by the COFACTOR algorithm. The 3D structure inside the box on the right of the figure was zoomed and rotated to be viewed from the citoplasmic side of the protein, focusing on the binding regions. Blue: residues binding metal clusters, red: residues binding phosphate.Back to article page
