Reactivity of Water Molecules in Macromolecules

The considerations of the preceding subsections stress the importance of the stractural flexibility provided by the extended and dense H-bond network developed by H2O molecules in macromolecules to ensure the stabihty of some of these macromolecules, particularly biomacromolecules. The representative case is the secondary structure of proteins, which requires the presence of such a network to be stable. This H-bond network does not [Pg.268]

The initial Rq-CO-NH-Ri peptide group to be hydrolysed is held fixed in a niche of the enzyme drawn as a cavity formed by the enzyme around the Rq group in I. It is surrounded [Pg.270]

It has been mentioned in Ch. 6 that these transfers of H-atoms are poorly known. They consequently need an important effort before they can be understood, so that such related quantities as typical times, numbers of participating H2O molecules, effect of temperature, etc. become known. Such methods as IR spectrometry, both conventional and nonlinear time-resolved, will certainly be the basic experimental methods to precisely observe these transfers. Theoretical accompanying developments are likely to be also useful. On which H-bonded systems will these mechanisms be observed No precise answer can be given, but recent hydration experiments, such as that of HA described above, may already give [Pg.272]
