Post-translational modifications (PTMs) are the covalent processes of changing proteins following their synthesis, and release from ribosomes.

Posttranslational modifications (PTMs) refer to amino acid side chain modification in some proteins after their biosynthesis. There are more than 400 different types of PTMs affecting many aspects of …

Besides single modifications, proteins are often modified through a combination of post-translational cleavage and the addition of functional groups through a step-wise mechanism of protein maturation …

Posttranslational modifications (PTMs) refer to the chemical modifications that occur on specific amino acids of a protein after translation, including processes such as phosphorylation, methylation, and …

Through chemical changes that occur after protein assembly—collectively known as post-translational modifications (PTMs)—cells exponentially expand protein functionality.

Jan 8, 2026 · Post-translational modifications are modifications that occur on a protein, catalysed by enzymes, after its translation by ribosomes is complete.

Jul 24, 2025 · These alterations, known as post-translational modifications, are chemical changes that occur to a protein after it has been synthesized, profoundly influencing its final form and activity. Post …

Protein posttranslational modifications (PTMs) refer to the breaking or generation of covalent bonds on the backbones or amino acid side chains of proteins and expand the diversity of proteins, which …

Oct 18, 2024 · Post-translational modifications refer to the covalent processing of proteins after they are translated from mRNA on ribosomes. These modifications involve the addition or removal of specific …

Aug 5, 2025 · Post-translational modification (PTM) refers to chemical changes that occur to a protein after it has been created by ribosomes, the cell’s protein-making machinery. Proteins are initially …
