REMARK 400 PROTEIN DATA BANK ENTRIES 2HHB AND 1HHB) AND ONE FOR REMARK 400 LIGANDED HEMOGLOBIN (THE R STATE, E.G. ENTRY 1HHO). THIS REMARK 400 STRUCTURE OF HUMAN CARBONMONOXYHEMOGLOBIN REPRESENTS A REMARK 400 SECOND QUATERNARY STRUCTURE (TERMED THE R2-STATE) FOR REMARK 400 LIGANDED HUMAN HEMOGLOBIN. IT IS SIMILAR, BUT NOT REMARK 400 IDENTICAL, TO THE LIGANDED STRUCTURE OF A NATURALLY REMARK 400 OCCURRING MUTANT HEMOGLOBIN, HEMOGLOBIN YPSILANTI (ENTRY REMARK 400 1CMY).
