Physical properties of thymus nucleoprotein
Biochimica et Biophysica Acta, 1954Abstract 1. 1. Nucleoprotein prepared by washing with dilute salt solution and extracting with water can be obtained mainly in the form of a highly aggregated gel-like material. 2. 2. The dispersed nucleoprotein obtained by several previous investigators is probably formed by enzymic degradation of the gel-like material.

Raman Spectroscopy of Proteins and Nucleoproteins
Current Protocols in Protein Science, 2013AbstractA protein Raman spectrum comprises discrete bands representing vibrational modes of the peptide backbone and its side chains. The spectral positions, intensities, and polarizations of the Raman bands are sensitive to protein secondary, tertiary, and quaternary structures and to side‐chain orientations and local environments. In favorable cases,

In vitro selection of nucleoprotein enzymes
Nature Biotechnology, 2001Natural nucleic acids frequently rely on proteins for stabilization or catalytic activity. In contrast, nucleic acids selected in vitro can catalyze a wide range of reactions even in the absence of proteins. To augment selected nucleic acids with protein functionalities, we have developed a technique for the selection of protein-dependent ribozyme ...

Nucleoprotein Layer of the Yeast Cell
Nature, 1963ELECTRON microscopy of yeast has revealed nucleic acid in a space between the cell-wall and the plasma-membrane. Fig. 1 shows: (a) the thin, double-walled, convoluted, nucleic acid-free, plasma-membrane; (b) a region (occupying almost one-tenth the total cell volume) rich in nucleic acid which lies outside the plasma-membrane directly beneath the cell ...

Our roots reach back to the depths of the past. The grand process — at least within our view of space and time — seems to have endeavored over a period of 10–20 billion years to gain a certain consciousness and understanding of itself. Together with the universe, life patterns originated in their early infancy from an alien phase transition between ...

Expression of mammalian spermatozoal nucleoproteins
Microscopy Research and Technique, 2003AbstractA dramatic remodeling of sperm chromatin occurs during mammalian spermiogenesis. Nuclear elongation and chromatin condensation are concomitant with modifications in the basic protein complement associated with DNA. A number of biochemical events accompany the displacement of histones and the appearance of protamines in elongating spermatids ...

Enzymic degradation of thymus nucleoprotein
Biochimica et Biophysica Acta, 1963Abstract Gel-forming deoxyribonucleprotein from calf thymus was treated separately with DNAase II, trypsin and chymotrypsin. The rate of decrease in rigidity and viscosity, the solubilization of DNA and histone products, and the hydrolysis of peptide bonds were followed. 1. 1. A complete loss of rigidity was obtained either by the scission of the
