== Function ==

'''Lysin''' (Lys) is a protein which cleaves cell walls.  Egg  Lysin, a protein from abalone sperm, creates a hole in the envelope of the egg, permitting the sperm to pass through the envelope and fuse with the egg.

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.
