Post-translational modification (PTM) is the covalent and generally enzymatic modification of proteins following protein biosynthesis. This process occurs in the endoplasmic reticulum and the golgi apparatus. Proteins are synthesized by ribosomes translating mRNA into polypeptide chains, which may then undergo PTM to form the mature protein product. PTMs are important components in c… Webb1 juni 2024 · CF is a chronic disease that affects 30,000 Americans and less than a million cases per year in India. CF is also a result of protein misfolding.
