Short strong hydrogen bonds in proteins: a case study of rhamnogalacturonan acetylesterase
{{output}}
An extremely low-field signal (at approximately 18 p.p.m.) in the (1)H NMR spectrum of rhamnogalacturonan acetylesterase (RGAE) shows the presence of a short strong hydrogen bond in the structure. This signal was also present in the mutant RGAE D192N, in which... ...
