What does phosphate do to amino acids?
What does phosphate do to amino acids? The addition of a phosphate (PO43-) molecule to a non-polar R group of an amino acid residue can turn a hydrophobic portion of a protein into a polar and extremely hydrophilic portion of a molecule. Are phosphorylated amino acids negatively charged? Protein phosphorylation provides a mechanism for the rapid, reversible control of protein function. Phosphorylation adds negative charge to amino acid side chains, and negatively charged amino acids (Asp/Glu) can sometimes mimic the phosphorylated state of a protein. What are the cationic amino acids? mM concentration of the cationic amino acids lysine (Lys),...
