Ribosomes, ribosomal subunits and ribosomal proteins of Lactococcus lactis IL1403

Biochimie, 1992
Abstract The preparation of ribosomes and ribosomal subunits of Lactococcus lactis and the characterization of the proteins of the subunits by one- and two-dimensional polyacrylamide gel electrophoresis and ion exchange chromatography are described.

The synthesis of ribosomal protein

Journal of Theoretical Biology, 1965
Abstract The hypothesis that nascent R-RNA associated with neosomes forms the unit responsible for the synthesis of ribosomal protein leads to a number of self-consistent relationships. The RNA of a 70 s ribosome is long enough to act as template for six molecules of ribosomal protein.

Ribosomal proteins and the conformation of ribosomal ribonucleic acid

Journal of Molecular Biology, 1971
Abstract Heat-denatured 16 s ribosomal RNA from Escherichia coli will combine with the total 30 s ribosomal proteins to form partially active 30 s ribosomes. The reconstitution process results in a change in the structure of the RNA, which can be demonstrated by chromatography on columns of methylated albuminkieselguhr.

Ribosomal proteins

Journal of Molecular Biology, 1973
Abstract Isolation of ribosomal precursors from Escherichia coli K12 is described. The RNA and protein content of the precursor particles was determined. One physiologically stable precursor was found for the 30 S subunit. The assembly scheme is as follows: p16 S RNA + 9 proteins → p30 S (“21 S” precursor) p30 S + 12 proteins → 30 S subunit where ...

A comparison of accessibility of ribosomal proteins on free and membrane-bound ribosomes: The ribosomal proteins potentially involved in ribosome-membrane binding

Biochimica et Biophysica Acta (BBA) - Gene Structure and Expression, 1987
The relative accessibility of rat liver ribosomal proteins to reductive methylation was examined using membrane-bound and free ribosomes. Comparisons indicated that 12-13 large ribosomal proteins are masked by ribosomal association with membranes. These consisted of L8, L10, L17, L26-28, L31 and L36, and probably also include L4, L5, L7 and L29.

Protein Kinase Associated with Ribosomes Phosphorylates Ribosomal Proteins ofStreptomyces collinus

Biochemical and Biophysical Research Communications, 1997
Protein kinase activity associated with ribosomes of a kirromycin-producing strain of Streptomyces collinus was detected. The enzyme utilizes [gamma-32P]ATP to phosphorylate proteins, yielding acid-stable phosphoamino acids. Two-dimensional electrophoresis of proteins from a crude ribosomal fraction revealed 17 phosphoproteins.

Crystallization of Ribosomes, Ribosomal Subunits, and Individual Ribosomal Proteins

1991
There is interest in the three-dimensional structure of the ribosome since it is a unique multicomponent biological system responsible for the biosynthesis of protein in the cell. The exceedingly complex structure of ribosomes (for example, the Escherichia coli ribosome, the molecular weight of which is 2.15•106 Da, consists of three types of RNA and ...

Ribosomal proteins. XXV. Immunological studies on Escherichia coli ribosomal proteins

Journal of Molecular Biology, 1971
Abstract Antisera specific for each of the twenty-one 30 s proteins and for 24 50 s ribosomal proteins of Escherichia coli were prepared and used to investigate whether there are any extensive sequence homologies between the different proteins. No immunological cross-reactions were detected between any of the proteins, except L7 and L12 which gave

[55] Phosphorylation of ribosomal proteins: preparation of rat liver ribosomal protein kinases. Assay of the phosphorylation of ribosomal subunit proteins. Assay of the function of phosphorylated ribosomes

1974
Publisher Summary The proteins of eukaryotic ribosomes are phosphorylated in vivo and in vitro . In the latter case the reaction is catalyzed by protein kinases present in the cytosol or associated with ribosomes. Two such enzymes, both stimulated by cyclic adenosine 3', 5’-monophosphate (cyclic AMP), can be isolated from rat liver cytosol; the ...
