Chromophore binding pocket of Acmaeodera diffusa UVS2, two views shown. Retinal is in orange. The residues shown comprise the chromophore binding pocket, as predicted by COACH (within 4 angstroms of retinal). Residues and their side chains in green are those reported as potentially significant to spectral tuning in Buprestidae, as listed in Table 2. Numbering is according to bovine rhodopsin
