During the germination and seedling growth of soybeans (Glycine max) a new form of the Kunitz soybean trypsin inhibitor (KSTI) appears in the cotyledons distinct from the KSTI of the quiescent inhibitor has been purified from the germinated seeds of soybean cultivar Amsoy 71 and cultivar Fiskeby by: During the germination and seedling growth of soybeans (Glycine max) a new form of the Kunitz soybean trypsin inhibitor (KSTI) appears in the cotyledons distinct from the KSTI of the quiescent seed.

This inhibitor has been purified from the. Proteolysis of kunitz soybean trypsin inhibitor during germination. Protease K1 activity initiates the degradation of the Kunitz soybean trypsin inhibitor (KSTI) during germination and early seedling growth.

This enzyme was purified nearly fold from the cotyledons of 4-day-old soybean (Glycine max [L.] Merrill) seedlings. Protease K1 is a cysteine protease with a molecular weight of approximatCited by:   The Bowman—Birk type trypsin inhibitor, BBSTI-D, which appears in the cotyledons of germinated soybeans (Glycine max), was isolated in homogeneous for Cited by:   In this paper, we also followed changing levels of these other Bowman-Birk isoinhibitors during germination and early growth.

We have recently described three enzymatic activities in the soybean which degrade the Kunitz inhibitors [7]. The degradation of the Bowman-Birk trypsin inhibitors is compared to that of the Kunitz trypsin inhibitors.

The cotyledons of the soybean (Glycine max [L.] Merrill cv Amsoy 71) were examined for proteolytic activities capable of degrading soybean seed proteins. Three distinct activities were identified that attack the native Kunitz soybean trypsin inhibitor of Am Tia. Protease K1 cleaves Tia to Tiam, the inhibitor form lacking the five carboxyl-terminal amino acid residues relative to Tia.

A kDa serine protease is implicated in tracheary element (TE) cell death and a soybean trypsin inhibitor can inhibit trypsin-triggered cell death mimicking PCD of TEs (Groover and Jones, ).
