Yeast nucleosomal particles: structural and transcriptional properties
Biochemistry, 1991Yeast nucleosomal core particles have been characterized by thermal denaturation, circular dichroism, and digestion with DNase I and with trypsin. Practically all nucleosomal DNA melts in one transition centered at 70 degrees C, and the circular dichroism spectrum is displaced to lower wavelengths as compared to that corresponding to chicken ...

Maturation of pre‐40S particles in yeast and humans
WIREs RNA, 2018The synthesis of ribosomal subunits in eukaryotes requires the interplay of numerous maturation and assembly factors (AFs) that intervene in the insertion of ribosomal proteins within pre‐ribosomal particles, the ribosomal subunit precursors, as well as in pre‐ribosomal RNA (rRNA) processing and folding.

A Protein Transformation Protocol for Introducing Yeast Prion Particles into Yeast
2010A range of methods for transforming organisms with nucleic acids has been established. However, techniques for introducing proteins, or particularly protein aggregates, into cells are less developed. Here, we introduce a highly efficient protocol for introducing protein aggregates such as prions into yeast.

The structures resulting from convective-sedimentation assembly (CSA) of bimodal suspensions (4.1-10% solids) of strongly charged sulfate latex microspheres (zeta potential -55.9±1.8 mV at pH 8.0) and weakly charged Saccharomyces cerevisiae (zeta potential -18.7±0.71 mV at pH 8.0) on glass, polyester, polypropylene, and aluminum foil substrates was ...

[26] Yeast mitochondria and submitochondrial particles
1967Publisher Summary Mitochondria and submitochondrial particles have been prepared from several species of yeast, including Candida (Torulopsis) utilis , Saccharomyces cerevisiae , and closely related species such as S. carlsbergensis . The foremost experimental obstacle in the preparation of intact yeast mitochondria is the need for efficiently ...

Chromosome-like particles during meiosis in fission yeast
Archives of Microbiology, 1974Chromosome-like structures were observed in spheroplasts ofSchizosaccharomyces pombe shortly before, or after the first meiotic division. From the work at hand, a number of six is considered to be the best estimate of a haploid set of chromosomes in this yeast.

Yeast-Expressed Bacteriophage-Like Particles for the Packaging of Nanomaterials
Molecular Biotechnology, 2013Virus-like particles (VLPs) generated by heterologous expression of viral structural genes have become powerful tools in vaccine development. Recently, we and others have reported on the assembly of VLPs of the RNA bacteriophages MS2, Qβ, and GA in yeast.

Characterization of lipid particles of the yeast, Saccharomyces cerevisiae
Yeast, 1994AbstractLipid particles of the yeast, Saccharomyces cerevisiae, were isolated to high purity and their components were analysed. The hydrophobic core of this organelle consists of triacylglycerols and steryl esters, which are almost exclusively located to that compartment. Lipid particles are stabilized by a surface membrane consisting of phospholipids

UCP3 Expressed in Yeast Is Primarily Localized in Extramitochondrial Particles
Biochemical and Biophysical Research Communications, 2001Previously it was concluded (1) that, differently from UCP1, on expression in Saccharomyces cerevisiae, UCP3, and UCP3 short (UCP3s) are in a deranged state, allowing for unregulated uncoupling. Here we show that the bulk of UCP3 and UCP3s is in extramitochondrial aggregates whether expressed with high or medium expression vectors.

Structures of the Yeast Proteasome Core Particle in Complex with Inhibitors
2004Intracellular proteolysis is an essential process (1). The ubiquitin—proteasome pathway represents a strictly controlled complex enzymatic machinery for nonlysosomal protein degradation in eukaryotic cells. Thus, it is particularly important for the turnover of many critical proteins controlling a vast array of biologic pathways, including ...
