Fig. 4From: Genomic exaptation enables Lasius niger adaptation to urban environmentsPositive (highlighted in red and orange) and negative (highlighted in blue) selected amino acids of CYP9 L. niger. Ligand-binding pocket is located in the upper right part of the protein molecule, with heme group in the bottom of the pocket. Most sites under positive selection are in the ligand-binding pocket, while structural alpha spiral domains are under purifing selectionBack to article page
