Papain's three-dimensional structure is at 1.65 Angstrom resolution. It consists of one polypepetide chain that is made up of 212 amino acids residues. There are three <scene name='Sandbox_37/Papain_disulfide_bonds/1'>disulfide bonds</scene> present in the enzyme that maintains the protein's structure. | Papain's three-dimensional structure is at 1.65 Angstrom resolution. It consists of one polypepetide chain that is made up of 212 amino acids residues. There are three <scene name='Sandbox_37/Papain_disulfide_bonds/1'>disulfide bonds</scene> present in the enzyme that maintains the protein's structure. Papain consists of 25% alpha helices and 21% beta sheets within its <scene name='Sandbox_37/Papain_beta-alpha/1'>secondary structure</scene>. Alpha helices are shown in red and beta sheets are shown in green. The enzyme's structure has a mixture of <scene name='Sandbox_37/Papain_hydrophobic/7'>hydrophobic residues</scene> shown in yellow and hydrophilic residues shown in purple. This corresponds to the protein's <scene name='Sandbox_37/Papain_polar/1'>polar residues</scene> shown in orange and nonpolar residues shown in green. | ||
