High Affinity of the 5-Upstream Region of a Winged Bean Chymotrypsin Inhibitor Gene for Nuclear Matrix
نویسندگان
چکیده
The 5-upstream region of a winged bean chymotrypsin inhibitor gene (JVCI-3b) was found to have a high affinity for nuclear matrix. The region, named WCI-3b MAR (matrix attachment region), is highly A + T-rich and contains multiple sites interacting with nuclear matrix. A MAR was also found in the corresponding region of the WCI-x gene, another active gene of the WCI family. Several MAR-binding proteins were detected in the wheat nuclear matrix.

Low Trypsin Inhibitors and Chymotrypsin Inhibitors in Winged Bean Mutants
In present studies several attempts have been made to reduce the amount of trypsin and chymotrypsin inhibitors in winged bean (Psophocarpus tetragonolobus) mutants developed through induced mutation. The low seed TI (trypsin inhibitor) lines comprised long pod-5 and long pod-2 mutant lines. The low tuber TI feature could be noted in the mutant population. Such lines were long pod-5, large leaf/...

A 516-bp winged bean chymotrypsin-trypsin inhibitor (WbCTI) gene was amplified from genomic DNA and cDNA isolated from winged bean using a pair of degenerate primers designed on the basis of the amino acid sequences of WbCTI. The amplified PCR products were cloned and sequenced to confirm their authenticity. DNA sequence analysis of the genomic and cDNA clones of WbCTI revealed the same nucleot...

The effects of deleting DNA sequences upstream from the phytohemagglutinin-L gene of Phaseolus vulgaris have been examined with respect to the level of gene product produced in the seeds of transgenic tobacco. Our studies indicate that several upstream regions quantitatively modulate expression. Between -1000 and -675, a negative regulatory element reduces expression approximately threefold rel...

An acidic lectin (WBA II) was isolated to homogeneity from the crude seed extract of the winged bean (Psophocarpus tetragonolobus) by affinity chromatography on lactosylaminoethyl-Bio-Gel. Binding of WBA II to human erythrocytes of type-A, -B and -O blood groups showed the presence of 10(5) receptors/cell, with high association constants (10(6)-10(8) M-1). Competitive binding studies with blood...

The subtilisin inhibitor (MBSI-A) from the mung bean (Vigna radiata (L.) Wilczek) seed has been purified to homogeneity. MBSI-A consists of a single polypeptide chain of 119 residues, with a high content of glutamic acid/glutamine, aspartic acid/asparagine, valine, threonine, and proline (19, 12, 10, 9, and 8 residue percent, respectively). MBSI-A is a potent inhibitor of subtilisin Carlsberg, ...
