Water 127-132 carbonic anhydrase 2 Homo sapiens 228-231 30089212-3 2018 With increasing Ca2+ concentration, both the chiral and achiral water vibrational signals had similar concentration-dependent changes, i.e., an initial decreasing phase followed by an increasing phase. Water 64-69 carbonic anhydrase 2 Homo sapiens 16-19
