Inverted Repeats
Inverted repeats are another form of repetitive DNA sequence[28]. Perfect inverted repeats of at least 10 bases separated by 50 residues or less were catalogued[17]. Few repeats longer than 15 bases were observed. The locations of the encoded amino acids are distributed throughout the module, in loops and secondary structures, and usually did not significantly change the composition or length of the protein sequence (Supplementary Data File 1).
