vicilin/glycine max

The G2 (A2B1a) glycinin subunit from soybean (Glycine max L. Merr.) was purified and renatured to the homohexameric holoprotein. This protein along with purified beta-conglycinin were subjected to limited proteolysis by trypsin. The generated polypeptide fragments were separated via SDS/PAGE and the

The 7S and 3S globulin fractions were extracted and characterized from Avena sativa L. seeds which showed similar solubility characteristics and holoprotein size to those of the vicilin fraction in legumes. These holoproteins were characterized by sodium dodecyl sulfate-polyacrylamide gel

The sequence of a gene encoding convicilin, a seed storage protein in pea (Pisum sativum L.), is reported. This gene, designated cvcA, is one of a sub-family of two active genes. The transcription start of cvcA was mapped. Convicilin genes are expressed in developing pea seed cotyledons, with

In this study, a single, improved methodology was used to extract, fractionate and purify the 11S (legumin-type or related to the alpha-conglutin from Lupinus albus L.), 7S (vicilin-type or related to the beta-conglutin from L. albus) and 2S (related to the gamma-conglutin from L. albus) families of

Protease C1, an enzyme from soybean (Glycine max [L.] Merrill cv Amsoy 71) seedling cotyledons, was previously determined to be the enzyme responsible for the initial degradation of the alpha' and alpha subunits, but not the beta subunit, of beta-conglycinin storage protein. The sizes of the

The protease that degrades the beta subunit of the soybean (Glycine max (L.) Merrill) storage protein beta-conglycinin was purified from the cotyledons of seedlings grown for 12 days. The enzyme was named protease C2 because it is the second enzyme to cleave the beta-conglycinin storage protein, the

A cDNA coding for a 54 kDa signal sequence containing protein has been isolated from a faba bean cotyledonary library and characterized. The deduced protein is designated Vicia faba SBP-like protein (VfSBPL) since it shares 58% homology to a 62 kDa soybean (Glycine max) protein (GmSBP) which has

In maturing seed cells, proteins that accumulate in the protein storage vacuoles (PSVs) are synthesized on the endoplasmic reticulum (ER) and transported by vesicles to the PSVs. Vacuolar sorting determinants (VSDs) which are usually amino acid sequences of short or moderate length direct the

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
