Mass spectrometry of ribosomes and ribosomal subunits.
Nanoflow electrospray ionization has been used to introduce intact Escherichia coli ribosomes into the ion source of a mass spectrometer. Mass spectra of remarkable quality result from a partial, but selective, dissociation of the particles within the mass spectrometer. Peaks in the spectra have been assigned to individual ribosomal proteins and to noncovalent complexes of up to five component ...
متن کاملStepwise Splitting of Ribosomal Proteins from Yeast Ribosomes by LiCl
Structural studies have revealed that the core of the ribosome structure is conserved among ribosomes of all kingdoms. Kingdom-specific ribosomal proteins (r-proteins) are located in peripheral parts of the ribosome. In this work, the interactions between rRNA and r-proteins of eukaryote Saccharomyces cerevisiae ribosome were investigated applying LiCl induced splitting and quantitative mass sp...
متن کاملHeat-shock-induced proteins from Myxococcus xanthus.
Optimal conditions for two-dimensional gel electrophoresis of total cellular proteins from Myxococcus xanthus were established. Using these conditions, we analyzed protein patterns of heat-shocked M. xanthus cells. Eighteen major spots and 15 minor spots were found to be induced by heat shock. From N-terminal sequences of 15 major spots, DnaK, GroEL, GroES, alkyl hydroperoxide reductase, aldehy...
متن کاملIsolation and characterization of mitochondrial ribosomes and ribosomal subunits from Leishmania tarentolae.
We have analyzed Leishmania tarentolae mitochondrial ribonucleoprotein (RNP) complexes using the 9S small subunit (SSU) rRNA and the 12S large subunit (LSU) rRNA as markers, and have identified a 50S RNP particle as the putative mitochondrial monosome, a 40S particle as the putative LSU and a 30S particle as the putative SSU. These assignments are supported by morphological analysis by cryo-ele...
متن کاملAdenosine 3'5'-m onophosphate dependent phosphorylation of ribosomes and ribosomal subunits from bovine corpus luteum.
In a previous publication the purification and properties of two protein kinases (KI and KII) from a soluble fraction of bovine corpus luteum and the stimulation of the latter fol. Chem. 248,494-501). We have now studied the effects oc cyclic AMP and luteinizing hormone on ribosomal protein phosphorylation of corpus luteum by protein kinase II. Protein kinase II catalyzed the phosphorylation of...
