Method Abstract:"The GFP precursor molecule was synthesized from 26 fully protected segments in solution, and the final 238-residue peptide was treated with anhydrous hydrogen fluoride to obtain the precursor molecule of GFP containing two Cys(acetamidomethyl) residues."
Comments Abstract:"The present paper describes the total chemical synthesis of the precursor molecule of the Aequorea green fluorescent protein (GFP). The molecule is made up of 238 amino acid residues in a single polypeptide chain and is nonfluorescent." p.13549 right column 2nd paragraph:"Aequorea GFP consists of 238 amino acid residues in a single polypeptide chain (primary sources). The native molecule has been shown to regenerate its intrinsic fluorescence from the totally denatured state (ref 10)."
