Engineering tyrosine-based electron flow pathways in proteins: The case of aplysia myoglobin [PDF]

, 2012
Tyrosine residues can act as redox cofactors that provide an electron transfer ("hole-hopping") route that enhances the rate of ferryl heme iron reduction by externally added reductants, for example, ascorbate.

Effects of Feeding Low Protein Diets with Different Energy-to-Protein Ratios on Performance, Carcass Characteristics, and Nitrogen Excretion of Broilers

Animals, 2023
This study shows the effects of feeding low protein (LP) diets with different energy-to-protein ratios were evaluated on the production parameters, carcass composition, meat quality, nitrogen retention, and excreta composition of broilers. A total of 576-

Responses of fast and slow growth broilers fed all vegetable diets with variable ideal protein profiles

, 2010
One thousand eight hundred and ninety male broilers of two strain crosses (fast and slow initial growth) were fed different ideal protein profiles in four-phase feed programs: 1 to 7, 8 to 21, 22 to 34 and 35 to 40 days of age.

Ideal architecture of residue packing and its observation in protein structures [PDF]

Protein Science, 1997
AbstractA simple model of sphere packing has been investigated as an ideal model for long‐range interactions for the packing of non‐bonded residues in protein structures. By superposing all residues, the geometry of packing around a central residue is investigated.

The cytoskeletal control of B cell receptor and integrin signaling in normal B cells and chronic lymphocytic leukemia

FEBS Letters, EarlyView.
In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.
