posttranslacyjna
Posttranslacyjna refers to modifications that occur to a protein after its synthesis, a process known as translation. These changes are crucial for a protein's function, stability, localization, and interaction with other molecules. While the genetic code dictates the amino acid sequence of a protein, post-translational modifications allow for a far greater diversity of protein structures and functions than would be possible from the 20 standard amino acids alone.
There are hundreds of known post-translational modifications, each with distinct biochemical mechanisms and biological consequences. Common
These modifications can occur at specific amino acid residues and can be reversible, allowing for dynamic control
