An integrated method of isolating napin and cruciferin from defatted canola meal

LWT - Food Science and Technology, 2015
Abstract Canola proteins are known to have great potential for use in food and non-food applications due to their nutritional, biological and functional properties. However, canola protein extraction remains a challenge, due mainly to the complexity of canola proteins and the presence a variety of undesirable compounds.

Proteomic identification of allergenic seed proteins, napin and cruciferin, from cold-pressed rapeseed oils.

Food Chemistry, 2015
In Finland and France atopic children commonly react to seeds of oilseed rape and turnip rape in skin prick tests (SPT) and open food challenges. These seeds are not as such in dietary use and therefore the routes of sensitization are unknown. Possible allergens were extracted from commercial cold-pressed and refined rapeseed oils and identified by gel-

In vitro refolded napin-like protein of Momordica charantia expressed in Escherichia coli displays properties of native napin

Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2006
Napins belong to the family of 2S albumin seed storage proteins and are shown to possess antifungal activity. Napins, in general, consist of two subunits (derived from single precursor) linked by disulphide bridges. Usually, reducing environment of the E.

Dynamic Light Scattering and NMR Studies of Napin

Journal of Solution Chemistry, 2002
We analyze the structure of napin (BngNAP1), a storage protein (m.w. 14.5 kDa) from Brassica napus. On the basis of the results of 1H NMR spectroscopy and dynamic light scattering (DLS) studies, the overall shape and secondary structure of the molecule are estimated.

Comparative structural, emulsifying, and biological properties of 2 major canola proteins, cruciferin and napin.

Journal of Food Science, 2008
ABSTRACT:  Canola is an economically important farm‐gate crop in Canada. To further explore the potential of canola protein as value‐added food and nutraceutical ingredients, a better understanding of fundamental properties of 2 major canola proteins is necessary.

Napin from Brassica juncea: Thermodynamic and structural analysis of stability

Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2007
The napin from Brassica juncea, oriental mustard, is highly thermostable, proteolysis resistant and allergenic in nature. It consists of two subunits - one small (29 amino acid residues) and one large (86 amino acids residues) - held together by disulfide bonds. The thermal unfolding of napin has been followed by differential scanning calorimetry (DSC)

Isolation and sequence analysis of napin seed specific promoter from Iranian Rapeseed (Brassica napus L.).

Gene, 2015
Rapeseed (Brassica napus L.) has become an important crop during the last 30years. In addition to a high lipid level, the seeds also have a significant protein content, which constitutes 20-25% of the dry seed weight. The synthesis of storage proteins is primarily controlled at transcriptional level and seed-specific expression has been shown to be ...

Seed-specific regulation of the napin promoter in Brassica napus

Journal of Plant Physiology, 1998
Summary The expression of the 2S storage protein napin in Brassica napus is dependent upon ABI3. Mutation analyses identified a promoter segment between −152 to −120, denoted the B-box, to be critical for the activity of the promoter in transgenic tobacco seeds. The B-box, which is highly conserved in all 2S promoters and which displays similarity to

Identification, characterization and epitope mapping of proteins encoded by putative allergenic napin genes from Brassica rapa

Clinical and Experimental Allergy, 2020
Brassica rapeseed crops contain high concentrations of oil in the seed. The remaining meal, following oil extraction, has a high protein content, but is of low value due to the presence of high amounts of napin seed storage proteins.

Napins, 2S albumins, are major allergens in oilseed rape and turnip rape

Journal of Allergy and Clinical Immunology, 2006
Children with IgE-mediated allergy to foods frequently react to seeds of oilseed rape (Brassica napus ssp. oleifera) and turnip rape (Brassica rapa ssp. oleifera) in skin prick tests (SPTs). Sensitization pathways are not known.We identified possible major allergens in oilseed rape and turnip rape using sera from 72 atopic children (mean age, 3.3 years)
