+The ARC-1 model has 6.4 monomer chains per turn (56.0 degrees rotation between monomers). This is more chains/turn than some previous type IV pilus models.
+To visualize chains/turn, we show <scene name='69/699340/Arc-1_no_hydrogen/18'>just one atom per protein monomer chain</scene> (alpha carbon of Phe51). Then these chain-marking-atoms are <scene name='69/699340/Arc-1_no_hydrogen/20'>connected with with rods</scene>, and the resulting helix is viewed from one end. When counting the chains/turn, bear in mind that the first and last (to complete one turn) count as 1/2 chain each.
