Being bored, he drew a polypeptide chain of roughly correct dimensions on a strip of paper and folded it into a helix, being careful to maintain the planar peptide bonds. Source: Internet
Biological functions Post-translational proteolytic processing Limited proteolysis of a polypeptide during or after translation in protein synthesis often occurs for many proteins. Source: Internet
Cleavage of polyproteins Some proteins and most eukaryotic polypeptide hormones are synthesized as a large precursor polypeptide known as a polyprotein that requires proteolytic cleavage into individual smaller polypeptide chains. Source: Internet
Crystallographic work has shown that there are no ribosomal proteins close to the reaction site for polypeptide synthesis. Source: Internet
He found that, as they dried, the amino acids formed long, often cross-linked, thread-like microscopic polypeptide globules, he named "proteinoid microspheres". Source: Internet
