The 7S and 11S seed storage proteins from four perennials related to soybean (Glycine canescens, G. tomentella, G. tabacina, and G. clandestina) were analyzed by sodium dodecyl sulfate-gel electrophoresis. Each species yielded a unique electrophoretic pattern that varied in the total number of bands and their relative mobilities. In every case, the electrophoretic patterns were substantially di...

Seed protein concentration of commercial soybean cultivars calculated on a dry weight basis ranges from approximately 37 to 42% depending on genotype and location. A concerted research effort is ongoing to further increase protein concentration. Several soybean plant introductions (PI) are known to contain greater than 50% protein. These PIs are exploited by breeders to incorporate the high-pro...

Various salt solutions used to hydrate full-fat cracked soybeans affected the thermal stability of both f)-conglycinin (75) and glycinin (115) storage proteins when examined by differential scanning calorimetry used to monitor both denaturation temperature (Td) and enthalpy (LiH). As salt ionic strength (fL) increased, the moisture in the hydrated beans decreased. When beans were hydrated with ...

The ontogeny of seed structure and the accumulation of seed storage substances is the result of a determinant genetic program. Using RNA interference, the synthesis of soybean (Glycine max) glycinin and conglycinin storage proteins has been suppressed. The storage protein knockdown (SP-) seeds are overtly identical to the wild type, maturing to similar size and weight, and in developmental onto...

The sorting determinants of glycinin, a soybean (Glycine max) 11S globulin, which mediates protein targeting to the protein storage vacuole (PSV), were investigated in maturing soybean cotyledons by transient expression assays. A C-terminal stretch of 10 amino acids of A1aB1b, a glycinin group I subunit, was sufficient to direct green fluorescent protein (GFP) to the PSV. This peptide may corre...

The amino acid sequence of the A3 subunit, an acidic subunit of the glycinin seed storage protein of the soybean (Glycine max (L.) Merrill), has been determined by sequence analysis of the peptides obtained by cyanogen bromide cleavage followed by enzymatic digestion and partial acid hydrolysis. The A3 subunit is composed of 410 amino acids (Mr approximately 46,000). It has been confirmed that ...

Soybeans (Glycine max) are an abundant source of proteins that have been recognized for their high nutritional value and bioactive properties. Soybeans are legumes, and possess high protein content (approximately 40%) as compared to most other legumes (Aguirre et al., 2008; Yimit et al., 2012). The health benefits of soybeans are attributed to the presence of bioactive compounds, and in particu...

The data information provided in this article relate to our research article "Using patient serum to epitope map soybean glycinins reveals common epitopes shared with many legumes and tree nuts" (Saeed et al., 2016) [1]. Here we provide western blot detection of glycinin subunits by soy-sensitive human sera, ELISA screens with overlapping synthetic peptides (epitope mapping), and various databa...
