WebPhosphorylation allows cells to accumulate sugars because the phosphate group prevents the molecules from diffusing back across their transporter. Phosphorylation of glucose is a key reaction in sugar metabolism. The chemical equation for the conversion of D-glucose to D-glucose-6-phosphate in the first step of glycolysis is given by: WebModel of phosphorylation cascade and viroplasm assembly. Based on our studies we hypothesize that dNSP2 autophosphorylates via the NTPase activity, creating a transient phosphohistidine intermediate. Autophosphorylated NSP2 remains dispersed in the cytoplasm and associates with hypophosphorylated NSP5. CK1α then phosphorylates …
