The isolation and characterization of a root lectin from soybean (Glycine max (L), cultivar Chippewa).
A lectin has been isolated from the roots of 5-day soybean (Glycine max (L) cultivar Chippewa) seedlings, and its properties have been compared to those of the soybean seed lectin. The sugar-binding activities of the two lectins, both in terms of specific hemagglutinating activity and sugar specificity, are indistinguishable. Molecular properties of the two lectins, measured as relative molecul...
متن کاملIsolation and Characterization of the Brassinosteroid Receptor Gene (GmBRI1) from Glycine max
Brassinosteroids (BRs) constitute a group of steroidal phytohormones that contribute to a wide range of plant growth and development functions. The genetic modulation of BR receptor genes, which play major roles in the BR signaling pathway, can create semi-dwarf plants that have great advantages in crop production. In this study, a brassinosteroid insensitive gene homologous with AtBRI1 and oth...
متن کاملPurification and Characterization of Hydroperoxidelyase from soybean (Glycine max)
A fatty acid hydroperoxidelyase (HPL) enzyme from soybean (Glycine max) seeds was purified by ammonium sulphate precipitation followed by ion exchange chromatography on DEAE-Cellulose and DEAE-Sephacel. HPL showed specific activity of 161U/mg with fold purification of 16.4 and enzyme yield was found to be 9.06%. The purified enzyme on SDSPAGE showed a prominent band of ~53KDa. Kinetic studies w...
متن کاملIsolation and characterization of a thiamin pyrophosphokinase gene, THI80, from Saccharomyces cerevisiae.
The thi80 mutant of Saccharomyces cerevisiae (Nishimura, H., Kawasaki, Y., Nosaka, K., Kaneko, Y., and Iwashima, A. (1991) J. Bacteriol. 173, 2716-2719) shows markedly reduced activity of thiamin pyrophosphokinase (TPK; EC 2.7.6.2). We have isolated a DNA fragment carrying the THI80 gene from a yeast genomic library by its ability to complement constitutive synthesis of the thiamin-repressible ...
متن کاملIsolation of low-molecular albumins of 2S fraction from soybean (Glycine max (L.) Merrill).
Numerous studies have shown that consumption of soybean products decrease the risk of cancers in humans. Experiments at the molecular level have demonstrated that in most cases proteins and peptides are responsible for the anticancer properties of soybeen. Special attention should be paid to lunasin - a peptide described for the first time 16 years ago. Due to its structure it causes i.a., inhi...
