Fig. 2From: Bioinformatics analysis of photoexcited natural flavonoid glycosides as the inhibitors for oropharyngeal HPV oncoproteinsThree-dimensional structure of proteins: a HPV-18 E6 oncoprotein (PDB ID: 4GIZ), b HPV-18 E7 oncoprotein (PDB ID: 6IWD). The HPV-18 E6 protein consists of a complex structure, including multiple alpha-D-glucopyranosyl chains and two zinc ions, and the HPV-18 E7 protein is composed of four chains, four phosphate ions, two chloride ions, and two zinc ionsBack to article page
