Soybean Kunitz trypsin inhibitor (SKTI), extracted from soybean (Glycine max L.) seeds, possesses insect resistance and anti-tumor properties. But its specific mechanisms of action are not yet known. This article reports an efficient method to produce recombinant SKTI (rSKTI) in Escherichia coli,
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 Amsoy 71, Ti(a). Protease K1 cleaves Ti(a) to
The soybean Kunitz trypsin inhibitor (KTi) has several polymorphic variants. Of these, Tia and Tib, which differ by nine amino acids, are the two main types. In this study, differences in KTi proteome between Tia and Tib were investigated using three soybean cultivars and three mutant lines. Two
Presence of Kunitz trypsin inhibitor (KTI) in soybean seeds necessitates pre-heat treatment of the soy-flour for its inactivation before using it in food and feed products. The heat treatment not only enhances processing costs of the soy-based foods and feeds but also affects seed-protein quality
Oligodeoxynucleotides complementary to the deduced mRNA sequence of soybean Kunitz trypsin inhibitor (KTI) were used to prime the synthesis of cDNA from soybean cotyledon total poly(A) RNA. The primed cDNA was used to select clones from a Glycine max cotyledon cDNA library. Two out of twelve
beta-Conglycinin (7 S globulin) and glycinin (11 S globulin) are the major reserve proteins of soybean. They were localized by the protein A immunogold method in thin sections of Glycine max (soybean) cv. Maple Arrow. In cotyledons, both globulins were simultaneously present in all protein bodies.
The soybean Bowman-Birk inhibitor (BBI), a polypeptide of MW 8,000, has a specificity directed against trypsin and chymotrypsin. BBI was localized at the ultrastructural level by the protein A gold method on thin sections of Glycine max (soybean) cv. Maple Arrow. In cotyledon and embryonic axis, BBI
The soybean (Glycine max (L.) Merrill) seed leucine aminopeptidase locus (Lap1) was found to be linked to the Kunitz trypsin inhibitor locus (Ti) with a recombination frequency of 15.3 percent +/- 0.9 percent. The two loci are in linkage group 9. Both Lap1 and Ti loci are inherited independently of
Changes in gene expression within roots of Glycine max (soybean), cv. Kent, susceptible to infection by Heterodera glycines (the soybean cyst nematode [SCN]), at 6, 12, and 24 h, and 2, 4, 6, and 8 days post-inoculation were monitored using microarrays containing more than 6,000 cDNA inserts.
The major trypsin inhibitor present in soybean [Glycine max (L.) Merrill] seed is the Kunitz trypsin inhibitor or soybean trypsin inhibitor A2 (SBTI-A2). Four forms of SBTI-A2 have been identified in the U.S. soybean germplasm collection. Three of the forms designated Ti(a), Ti(b), and Ti(c) are
The search for potent and selective therapeutic agents is progressing by the study of natural compounds in plants. Plant-derived macromolecules are considered emerging therapeutic agents and an alternative to synthetic and small molecule drugs. Where it has long been known that plants possess
Chickpea (Cicer arietinum L.) seeds contain Bowman-Birk proteinase inhibitors, which are ineffective against the digestive proteinases of larvae of the insect pest Helicoverpa armigera. We have identified and purified a low expressing proteinase inhibitor (PI), distinct from the Bowman-Birk
OBJECTIVE
This study was aimed to purify and characterize the Protease inhibitor (PI) from a plant Allium sativum (garlic) with strong medicinal properties and to explore its phytodrug potentials.
METHODS
Allium sativum Protease Inhibitor (ASPI) was purified using ammonium sulphate fractionation and
Molecular signaling interactions in the plant apoplast are important for defense and developmental responses. We examined the soybean proteome of the apoplastic conduit of root-to-shoot communication, the xylem stream, using gel electrophoresis combined with two types of tandem mass spectrometry. We
Soybean is recognized as a commonly allergenic food, but the identity of important allergens is not well studied. Recently, some global regulatory agencies started requiring quantitative analysis of individual allergens, including unproven allergens, as part of the risk assessment for genetically
