title: Protein conformation wheels: cytochromes and lysozymes.
abstract: Conformation wheels, directly relating to amino acid sequence to the local torsion angles in a protein molecule, are presented for cytochromes c, c2, c550, and c551 and for lysozymes from hen egg-white and T4 bacteriophage. The circular plots for the cytochrome molecules aid in visualizing the common three-dimensional folding ("cytochrome fold") observed in this family of proteins. Conformation wheels for lysozymes from two different species reveal the characteristic differences in their folding patterns. These novel plots are also useful in storing and comparing the several sets of crystallographic data reported for lysozyme.
