The secondary and 3D structures of COX1 of C. uncinata A There are 11 transmembrane segments in the secondary structure. Purple and blue letters represent nonpolar amino acids, while blue letters denote more hydrophobic amino acids than those in purple letters. Black letters indicate polar charged amino acids, and red letters indicate polar uncharged amino acids. B The 3D structure of COX1 predicted by Swiss-Model
