GMCP3 encodes a cystein proteinase of Glycine max belonging to the papain-like family (C1A in MEROPS database) that was previously found to be involved in the mobilization of protein reserves during seed germination. Here, we report that GMCP3 is induced by senescence and diverse stresses in
Two types of cysteine proteases, low-specificity enzymes from the papain family and Asn-specific from the legumain family are generally considered to be the major endopeptidases responsible for the degradation of seed storage proteins during early seedling growth. The action of the corresponding
Phytocystatins are cysteine proteinase inhibitors ubiquitously present in plants and animals. They are known to carry out various significant physiological functions and also maintain the balance of protease-antiprotease activity. In the present disquisition, a phytocystatin after preliminary
Cysteine proteases and cystatins have many functions that remain poorly characterised, particularly in crop plants. We therefore investigated the responses of these proteins to nitrogen deficiency in wild-type soybeans and in two independent transgenic soybean lines (OCI-1 and OCI-2) that express
The lectin of Erythrina corallodendron (Caesalpiniaceae) seeds was purified by heating, ammonium sulfate fractionation, and affinity chromatography on acid-treated Sepharose. The purified lectin is similar to the soybean lectin in being a glycoprotein of molecular weight around 110 000 - 120 000 and
Plant cystatins, also called phytocystatins constitute a family of specific cysteine protease inhibitors found in several monocots and dicots. In soybean, phytocystatins regulate several endogenous processes contributing immensely to this crop's tolerance to abiotic stress factors. Soybeans offer
The enzymatic properties of novel cysteine proteases D3-alpha and beta which were purified from germinating soybean cotyledons were investigated. The enzyme activities were exhibited in the presence of a thiol reagent, such as 2-mercaptoethanol, and apparently inhibited by E-64, a cysteine protease
As a protein-rich, underutilized crop, green soybean could be exploited to produce hydrolysates containing angiotensin-I converting enzyme (ACE) inhibitory peptides. Defatted green soybean was hydrolyzed using four different food-grade proteases (Alcalase, Papain, Flavourzyme and Bromelain) and
Diverse functions for three soybean (Glycine max L. Merr.) cysteine proteinase inhibitors (CysPIs) are inferred from unique characteristics of differential regulation of gene expression and inhibitory activities against specific Cys proteinases. Based on northern blot analyses, we found that the
Protein inhibitors of cysteine proteinases possessing unusual properties have been found in soya (Glycine max) seeds. One of the inhibitor forms has also been detected in Bowman-Birk inhibitor preparations (both commercial and purified by affinity chromatography on chymotrypsin-Sepharose ones). A
Phytocystatins play multiple roles in plant growth, development and resistance to pests and other environmental stresses. A ramie (Boehmeria nivea L.) phytocystatin gene, designated as BnCPI, was isolated from a ramie cDNA library and its full-length cDNA was obtained by rapid amplification of cDNA
cDNA clones for a putative cysteine proteinase were isolated from developing cotyledons of soybean (Glycine max.) using PCR-based techniques. The full-length clone of 1441 bp encodes a proteinase pre-propolypeptide of 380 amino acids. It belongs to the commonly known papain family and shows the
It has been well demonstrated that cystatins regulated plant stress tolerance through inhibiting the cysteine proteinase activity under environmental stress. However, there was limited information about the role of cystatins in plant alkali stress response, especially in wild soybean. Here, in this
Three cysteine proteinase inhibitor cDNA clones (pL1, pR1, and pN2) have been isolated from a soybean (Glycine max L. Merr.) embryo library. The proteins encoded by the clones are between 60 and 70% identical and contain the consensus QxVxG motif and W residue in the appropriate spatial context for
The increasing use of soybean (Glycine max) products in processed foods poses a potential threat to soybean-sensitive food-allergic individuals. In vitro assays on soybean seed proteins with sera from soybean-sensitive individuals have immunoglobulin E reactivity to abundant storage proteins and a
