| + | The structure of lysin, refined at 1.9 angstroms resolution, reveals an alpha-helical, amphipathic molecule. <scene name='60/607850/Alpha_helixes/1'>To see alpha helixes press here</scene>. you can see the alpha helixes in pink. <scene name='60/607850/Surface/1'>the surface of the protein</scene> exhibits three features: two tracks of basic residues that span the length of the molecule, a solvent-exposed cluster of <scene name='60/607850/Aromatic_and_aliphatic/1'>aromatic and aliphatic amino acids</scene>,(in green) and an extended amino-terminal hypervariable domain that is species-specific.
