Hemolysin is a protein produced by the bacteria Staphylococcus aureus. Seven subunits of hemolysin assemble into a heptamer complex that embeds itself into the membrane of a red blood cell. Each subunit contributes 2 strands to a 14-stranded beta-barrel that is inserted into the membrane to create a hole. Hemoglobin protein then leaks out of the red blood cells, making the iron available to the bacteria to support their growth.

Each of the 7 subunits in this 3-D protein model of hemolysin is displayed in a alpha carbon backbone format and colored differently (red, light green, orange, blue, light blue, purple, and green) to help your students see the individual subunits.

This 3.5'' model is made of plaster by rapid prototyping and should be handled with care. Mini models will break if dropped, held tightly or handled roughly. Its PDB file is 7AHL.pdb.
