AUTHOR HAS CONFIRMED THESE ATOMS AND STATED: 7 PROTEIN ATOMS WITH ZERO B FACTORS AFTER PHENIX REFINEMENT, FOUND TO POSSESS QUITE STRONG ELECTRON DENSITIES. THE 5 WATER MOLECULES WITH ZERO TEMPERATURE FACTORS COULD VERY WELL BE SODIUM CATIONS WHICH ARE ISO-ELECTRONIC WITH WATER OXYGEN ATOMS. HOWEVER NA+ IONS SHOULD HAVE HIGHER ELECTRON DENSITIES AT THEIR CENTERS COMPARED TO OXYGEN, DUE TO A HIGHER ATOMIC NUMBER.
