Molecular docking of a docosatrienoic acid (DTA, green sticks), b eicosatrienoic acid (ETA, magenta sticks), c linoleic acid (LA, cyan sticks) and d linolenic acid (LEA, light blue sticks) into the homology model of CaeLox1. Iron (orange) binding amino acid residues are highlighted as blue sticks (H338, H343, H523, N527, I656) and the positively charged amino acid at the bottom of the substrate tunnel is highlighted in yellow sticks. Amino acid residues involved in shaping the substrate tunnel are shown as red sticks (V581, I393 and W330). Oxygen inside the amino acid side chains are colored in red and nitrogen in blue
