WebThe phosphorylated proteins were adsorbed by ligand exchange of phosphate for hydroxyl even when an electrostatic repulsive force was present. However, the extent (adsorptive capacity) and strength (adsorptive coefficient) of adsorption was inversely related to the degree of phosphate substitution of the aluminum hydroxide adjuvant. WebBefore the ligand binds, the inactive G-protein can bind to a newly revealed site on the receptor specific for its binding. Once the G-protein binds to the receptor, the resulting change in shape activates the G-protein, which releases guanosine diphosphate (GDP) and picks up guanosine 3-phosphate (GTP). list of sbir companies
