Sequence identity within and between gene superfamilies signal peptide sequences. The minimum percentage of sequence identities computed between signal peptide sequences of precursor belonging to the same gene superfamily are on a black background. The maximum percentage identities measured between signal peptide sequences of precursors belonging to different gene superfamilies are on a white or gray background. Comparisons between the new gene superfamilies and the previously known gene superfamilies are highlighted on a gray background. The percentage of sequence identities were computed for all pairs of sequences using a Smith and Waterman algorithm, and the percentage of identity was computed using the length of the smallest sequence. The gene superfamily M was detailed into three branches: m-1, m-2 and m-c (conomarphins).
