The deproteinisation of nucleoproteins

Biochimica et Biophysica Acta, 1954
Abstract Various methods for the deproteinisation of the nucleoproteins of Myco. phlei, Aerobacter aerogenes and thymus have been studied in detail. The deproteinising agents investigated were strong salt solutions, chloroform and octanol ( Sevag et al. ), sodium dodecyl sulphare (S.D.S.) and chloral hydrate.

NUCLEOPROTEIN SYNTHESIS IN THE MITOCHONDRION

Canadian Journal of Genetics and Cytology, 1969
Lipolated (fat-filled) mitochondria in Saccharomyces have been observed both by light-microscopy and by electron-microscopy. Previous workers have shown, by ultraviolet-microscopy and by fat stains, using the light-microscope, that the lipolated mitochondria contain both lipids and ribonucleotides.

THE VIRUSES AS NUCLEOPROTEINS

Canadian Journal of Medical Sciences, 1953
A review of work in the bacteriophage field is presented. The discussion is concerned mainly with biochemical aspects of the problem but some reference is also made to genetic studies.

Expression of mammalian spermatozoal nucleoproteins

Microscopy Research and Technique, 2003
AbstractA 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 ...

Physical properties of thymus nucleoprotein

Biochimica et Biophysica Acta, 1954
Abstract 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, 2013
AbstractA 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,

Nucleoprotein Layer of the Yeast Cell

Nature, 1963
ELECTRON 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 ...

In vitro selection of nucleoprotein enzymes

Nature Biotechnology, 2001
Natural 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 ...
