post-translational modification


a: post-translational modification ~
b: ornaments on a tree


"Proteins are made from strings of amino acids according to directions encoded by the DNA in genes, but these proteins subsequently undergo important modifications. "When it is first translated from the genetic code, a protein is like a bare Christmas tree," Fisher says. "For any given protein encoded by the same genetic code, one protein molecule looks just like another. But the addition of small molecules through post-translational modification is like adding ornaments to the Christmas tree branches."
