[Comparative studies on the reactive sites against trypsin of some inhibitors from phaseolus coccineus and phaseolus vulgaris (author's transl)].

Three of the trypsin chymotrypsin inhibitors from the seeds of runner beans (Phaseolus coccineus L.), PCI 3,4(2), and 5, and three of the inhibitors from the seeds of french beans (Phaseolus vulgaris var. nanus), PVI 3, 4, and 5, contain a lysine residue in the reactive site against trypsin. One of the inhibitors from Phaseolus coccineus, PCI 2, contains an arginine residue there. All seven Phaseolus inhibitors investigated are double headed.
