Webb1 sep. 2024 · The primary structure of polypeptides and proteins is the sequence of amino acids in the polypeptide chain with reference to the locations of any disulfide bonds. The primary structure may be thought of as a complete description of all of the covalent bonding in a polypeptide chain or protein. WebbTranscription factors are proteins which bind to control regions of DNA. The RNA-binding two-helix protein Rom has already been mentioned. A three-helix bundle forms the basis of a DNA-binding domain which occurs in a number of proteins- for example homeodomain proteins. Examine the crystal structure of engrailed homeodomain binding to DNA.
