34374547-5	2021	We report the detection of frequency fluctuations of an azide anion (N3-) bound in the active site of the protein carbonic anhydrase II, where a low-frequency mode of the protein has been proposed to facilitate proton transfer over two water molecules during the catalyzed reaction.	Azides	56-67	carbonic anhydrase 2	Bos taurus	114-135
