Preliminary characterization of ssps (Seed Storage Proteins) IN Argania spinosa L
نویسندگان
چکیده
SSPs (Seed Storage Proteins) of the 11S type have been preliminary characterized in the seeds of the argan tree, an endemic species from Morocco. Protein extracts from mature seeds were prepared by using different solutions in order to assess the solubility of the major protein forms. SSPs of the 11S type were classified as albumins according to the further SDS-PAGE analysis of these extracts. The combination of both reducingand nonreducing conditions for the SDS-PAGE analysis, together with immunoblot experiments allowed us to determine the presence of three precursor forms of these proteins (pro1, pro2 and pro3), which are composed of six individual peptides (p1 to p6) in different combinations.

Structural Investigation of Cell Wall Xylan Polysaccharides from the Leaves of Algerian Argania spinosa.
Xylan-type polysaccharides were isolated from the leaves of Argania spinosa (L.) Skeels collected in the Tindouf area (southwestern Algeria). Xylan fractions were obtained by sequential alkaline extractions and purified on Sepharose CL-4B. The xylan structure was investigated by enzymatic hydrolysis with an endo-β(1→4)-xylanase followed by chromatography of the resulting fragments on Biogel P2,...

متن کاملCharacterization of seed storage proteins in Populus and their homology with Populus vegetative storage proteins.
We investigated the synthesis and accumulation of vegetative storage proteins (VSPs) in poplar plantlets and the homology between poplar seed storage proteins (SSPs) and VSPs. One-dimensional SDS polyacrylamide gel electrophoresis confirmed that both seed and vegetative storage proteins contained two predominant polypeptides of MW 32 and 36 kDa, but the subunit composition of the polypeptides d...

Argania spinosa is an evergreen tree endemic of southwestern Morocco. Many preparations have been used in traditional Moroccan medicine for centuries to treat several illnesses including diabetes. However, scientific evidence supporting these actions is lacking. Therefore, we prepared various extracts of the argan fruit, namely keel, cake and argan oil extracts, which we tested in the HTC hepat...
