Alignment of VP3 with coliphage internal scaffolding proteins. The amino acid sequence of the φX174 internal scaffolding protein was aligned to the first 120 amino acids of VP3 from Chp1 and Chp2. Amino acid variations found in the internal scaffolding proteins of bacteriophages G4 and α3 which show identity to the Chp1 and Chp2 proteins are indicated in the outer lines.
