WebAspartic acid is an amino acid having an acidic side chain CH2COOH. To calculate the isoelectric point for this amino acid, the pKa of the similarly ionizable groups will be considered which in this case are the carboxylic acid group (pKa = 1.88) and the acidic side chain (pKa = 3.65). pI=1.88 +3.652=2.77. Calculate the isoelectric point of Lysine WebHere we present the thermodynamic and functional characterization of an unnatural amino acid mutant at His37, where the imidazole side chain is substituted with a 4-thiazolyl group that is unable ...
