^a Percent similarity of amino acid sequence alignments from first methionine to stop codons; values in parentheses are percent identity from Helix 1 through Helix 7
^b Atomic values in angstroms, where the lower the RMSD value, the higher is the similarity between structures
^c Numbers in bold indicate minimum and maximum values
