Knowledge of both the packaging of the linear, double-stranded (ds)DNA in bacteriophages and its subsequent release into the bacterial host is vital to our understanding of phage infection. There is now strong evidence that packaging requires a power

Low-temperature heat capacity of biomacromolecules and the entropic cost of bound water in proteins and nucleic acids (DNA)

Autor: G. M. Mrevlishvili

Publikováno v: Thermochimica Acta. 308:49-54

On the basis of the heat capacity data for proteins and DNA, obtained in the wide temperature range (2–300 K), the amount of the entropic cost of bound water in biomacromolecules is determined. The entropic cost of transferring a single water molec
