10. Covalent post-translational modifications can alter the structure and function of proteins, allowing them to operate in specific regions of the cell, perform specific functions, or interact with specific proteins. In lecture, we discussed several types of covalent post-translational modifications and their roles in protein localization, folding, or function. Choose one example from each of the following categories and describe the modification and, generally, what it does the localization/function of the protein: glycosylation, lipidation, polypeptide attachment.
