The topological aspects of the conformational transformations in proteins are investigated using a new peptide‐ribbon representation of the tertiary structure. The topological parameters evaluated on a set of 49 proteins show striking regularities that extend beyond the secondary structures actually present and are interpreted as a manifestation of the topological invariance of conformational transformations in globular proteins.
