A novel fingerprint, defined without the use of distances, is introduced to characterize protein folds. It is of the form of binary matrices whose elements are defined by angles between the C=O direction, the backbone axis and the line connecting the
-carbons of the various residues. It is shown that matches in the fingerprint matrices correspond to low r.m.s.d.
