Differentiated analysis of the secondary structure of hydrophilic and hydrophobic regions in alpha- and beta-subunits of Na+,K+-ATPase by Raman spectroscopy.

abstract：:Crosslinking of histones in mouse liver nuclei and extended chromatin with a bifunctional reagent leads to the formation of H1-H1o heterodimers as well as H1o-H1o homodimers. H1o can be also crosslinked to the core histones. Thus, the location of histone H1o within the basic repeating chromatin structure seems to be a...
