In recent years, interest in plant-based proteins has been rising due to ethical and sustainability issues. In this context, the production of protein concentrates and isolates from new plant sources have increased enormously because of their nutritional and techno-functional properties. Therefore, this work describes a pilot process for obtaining protein-rich ingredients from a yellow lupin variety (Lupinus luteus) developed by the Agriaquaculture Nutritional Genomic Center (CGNA).

This work describes a chemical characterization and techno-functional properties (emulsifying and foaming properties) of 3 protein fractions obtained from a protein-rich novel lupin variety, AluProt-CGNA(®) . This nongenetically modified variety have a great protein content in dehulled seeds (60.

RNA-protein remodeling events required for spliceosome assembly, splicing catalysis, and spliceosome disassembly are driven and controlled by a conserved group of ATPases/RNA helicases. The activities of most of these enzymes are timed by their recruitment to the spliceosome.

Little is known about mechanisms of regulation of Ski2-like helicases by protein cofactors. Here we show by crystal structure and biochemical analyses that the Prp8 protein, a major regulator of the spliceosome, can insert its C-terminal tail into Brr2's RNA-binding tunnel, thereby intermittently blocking Brr2's RNA-binding, adenosine triphosphatase, and U4/U6 unwinding activities.
