title: Bowman-Birk type protease inhibitors: two-dimensional vector representation for their sequences.
abstract: The degree of structural similarity in the legume Bowman-Birk type protease inhibitors has been examined on the basis of two-dimensional vector representation of the respective amino acid sequences. Amino acid residue size and hydrophobicity are the two dimensions used (Swanson, R. (1984) Bull. Math. Biol., 46: 623-639). For the set of such homologous proteins a consensus sequence is generated. A non-negative real-valued function on the set of compared sequences is proposed as a measure of dissimilarity between compared sequences. In the group of those double-headed protease inhibitors sub-groups are distinguished presenting high structural similarity among their respective members and lower similarity among them.
