The bacterial protein called flagellin (molecular weight 40,000 g/mol) has been used to calculate the accuracy of protein synthesis. Flagellin offers two advantages, it can be easily obtained as a pure fraction and it contains no cysteine, thereby allowing a sensitive measure of the misincorporation of cysteine into the protein. […]
