a
Identity values are expressed as percentages calculated with the complete amino acid sequences, including the signal peptides. The values were derived by dividing the number of perfect matches by the length of the shorter sequence, excluding gaps, by a multiple-alignment method.
b
The accession number of IND-1 is AF099139.
