Biosynthesis of storage proteins in developing rice seeds.
Sodium dodecyl sulfate-polyacrylamide gel electrophoretic analysis of the starchy endosperm protein of rice (Oryza sativa L. Japonica cv Koshihikari) during seed development confirmed that storage protein begins to accumulate about 5 days after flowering. Two polypeptide groups, 22 to 23 and 37 to 39 kilodaltons, the components of glutelin, the major storage protein in rice seed, appeared 5 day...
متن کاملThiamin-binding protein from sunflower seeds.
A thiamin-binding protein was isolated from sunflower seeds. Its molecular mass was estimated to be 230 kDa by gel filtration. The protein was suggested to be composed of six subunits, which consisted of polypeptides linked by disulfide bond(s). The protein contained a large amount of glutamine or glutamic acid (19.9 mol%) and asparagine or aspartic acid (11.1 mol%). The levels of tryptophan an...
متن کاملTaurine TransportInhibitorySubstance in Sesame Seeds
An ethanol extract from sesame seeds inhibited the taurine uptake in human intestina) epithelial Caco-2 cells. The uptake of such a-amino acids as leucine and glutamic acid was not jnhibited by the extract, indicating that this inhibition is speeific to the taurine uptake. The llnknown inhibitor in the sesame extract was purjfied by reversed-phase HPLC by monitoring the inhibitory elkct on taur...
متن کاملAccumulation and degradation of thiamin-binding protein and level of thiamin in wheat seeds during seed maturation and germination.
Changes in the levels of thiamin-binding globulin and thiamin in wheat seeds during maturation and germination were studied. The thiamin-binding activity of the seed proteins increased with seed development after flowering. The thiamin content of the seeds also increased with development. Thiamin-binding activity decreased during seed germination. On the other hand, immunological analysis using...
متن کاملMechanism and regulation of galactomannan biosynthesis in developing leguminous seeds.
The galactomannans [ l ] are a group of watersoluble polysaccharides which are found in the endosperms of leguminous seeds. (Not all legume seeds are endospermic, but if an endosperm is present it will contain galactomannan). Structurally, legume-seed galactomannans comprise a linear ‘backbone’ of ( 1 + 4)-@-linked u-mannopyranosyl residues, which is laterally substituted by u-galactopyranosyl ...
