    Amino-acid sequence of two trypsin isoinhibitors, ITD I and ITD III from squash seeds (Cucurbita maxima).

    Wilusz T, Wieczorek M, Polanowski A, Denton A, Cook J, Laskowski M Jr.

    The amino-acid sequences of two trypsin isoinhibitors, ITD I and ITD III, from squash seeds (Cucurbita maxima) were determined. Both isoinhibitors contain 29 amino-acid residues, including 6 half cystine residues. They differ only by one amino acid. Lysine in position 9 of ITD III is substituted by glutamic acid in ITD I. Arginine in position 5 is present at the reactive site of both isoinhibitors. The previously published sequence of ITD III has been shown to be incorrect.
