You have identified a novel protein complex that forms a pore across the plasma membrane of a eukaryotic cell. The pore is made of five protein subunits, each of which contributes a membrane-spanning a helix to form the pore. Each a helix has hydrophilic amino acid side chains on one face of the helix and hydrophobic amino acid side chains on the opposite side.What is the likely arrangement of these five a helices in the membrane?
