What Is Post-Translational Modification?

Post-translational modification refers to chemical modification of a protein after translation. For most proteins, this is a later step in protein biosynthesis.

Post-translational modification

Right!

Post-translational modification refers to the post-translational modification of proteins

Precursor proteins are inactive and often undergo a series of post-translational processing to become functional mature proteins. There are various types of processing, which are generally divided into the following types: resection of N-terminal fMet or Met,

Post-translational modifications include the following additions

Interferon-activated geneticsestablished with interferon-activated gene 15 (ISG15) protein

Citrullination-convert arginine to citrulline. Deamination-convert glutamine to glutamic acid or asparagine to aspartic acid. Structurally altered disulfide bonds-covalent bonds with two cysteine amino acids. Break down proteins-cut the peptide bonds of proteins.
