| - | <scene name='74/744126/Pcna_monomer_helixfront_2/1'> The PCNA monomers </scene> consist of 258 residues each and are a mass of 28.916 kDa. Each monomer contributes two domains to the trimeric ring. These domains possess anti-parallel beta sheets (blue) which approach each other on one end, but are separated by two alpha helices at the other (red), creating a 45 degree wedge in the sheets with alpha helices at the blunt end. The domains are connected by an extended beta sheet. This creates a <scene name='74/744126/6_fold_symmetry/1'> six-fold symmetry within the trimeric ring </scene> and it also creates a β-α-β-β-β motif going around the ring. <ref>8001157</ref> | + | <scene name='74/744126/Pcna_monomer_helixfront_2/1'> The PCNA monomers </scene> consist of 258 residues each and are a mass of 28.916 kDa.

| - | This is a sample scene created with SAT to <scene name="/12/3456/Sample/1">color</scene> by Group, and another to make <scene name="/12/3456/Sample/2">a transparent representation</scene> of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes. | ||
