In this paper, we analyze the symmetries of beta-barrel proteins at both structure and sequence levels by using a modified recurrent quantification analysis. It shows that the structures and sequences have the same two-fold symmetry, although the later diverged considerably. This result may be helpful to understand the mechanism of protein evolution.
