The DsRed protein is a 28kDa | The DsRed fluorescent protein is a 28kDa polypeptide that emits a red color after an excitation because of the presents of a chromophore composed by 3 amino acids –Gln-Tyr-Gly- (residues 66-68). The fold of our protein is very closed to the most common fluorescent protein, the Aequorea victoria Green Fluorescent Protein (avGFP). The primary sequence of those two proteins is 23% similar but in the immediate vicinity of the chromophore the primary structure is strictly conserved and theses several amino acid are probably essential for the chromophore formation. The DsRed protein is obligatory a tetramer in solution. The monomer is composed by 11-strand beta barrel with a coaxial helix. | ||
