Porin is made of 18 beta strands surrounding a hydrophilic pore, which is charged and polar. The surface of porin is hydrophobic, because it interacts with neighboring alkane chains. | Porin is made of 18 beta strands surrounding a hydrophilic pore, which is charged and polar. The surface of porin is hydrophobic, because it interacts with neighboring alkane chains. In another <scene name='Sandbox12/Spacefill/2'>representation</scene> of the protein, the hydrophilic pore is visible in the porin. (There are three porins attached to each other in the image.) | ||
