Macromolecular Structure Assembly as a Novel Antibiotic Target
This review discusses the inhibition of macromolecular structure formation as a novel and under-investigated drug target. The disruption of cell wall structures by penicillin-binding protein interactions is one potential target.

Mass spectrometry of ribosomes and ribosomal subunits [PDF]
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.

The Effects of Deregulated Ribosomal Biogenesis in Cancer
Ribosomes are macromolecular ribonucleoprotein complexes assembled from RNA and proteins. Functional ribosomes arise from the nucleolus, require ribosomal RNA processing and the coordinated assembly of ribosomal proteins (RPs), and are frequently ...

Mediating Ribosomal Competition by Splitting Pools [PDF]
Synthetic biology constructs often rely upon the introduction of "circuit" genes into host cells, in order to express novel proteins and thus endow the host with a desired behavior. The expression of these new genes "consumes" existing resources in the cell, such as ATP, RNA polymerase, amino acids, and ribosomes. Ribosomal competition among strands of

Ribosomal Biogenesis and Heterogeneity in Development, Disease, and Aging
Although reported in the literature, ribosome heterogeneity is a phenomenon whose extent and implications in cell and organismal biology is not fully appreciated.

Nuclear 80S Ribosomes Present Across the Stages of Cell Cycle in Drosophila Melanogaster Cells
Nuclear translation has been a subject of controversy between scientists for over 5 decades. Despite the existence of evidence to the contrary, most biologists agree that translation exclusively takes place in the cytoplasm of eukaryotes.

The ABCs of the ribosome [PDF]
An ABC protein that binds the ribosomal exit site suggests a new mechanism for direct regulation of translation in response to changing ATP levels in the cell.

Isolation of biologically active cell components from multicellular eukaryotic organisms often poses difficult challenges such as low yields and inability to retain the integrity and functionality of the purified compound. We previously identified a cap-

Ribosomal proteins: functions beyond the ribosome [PDF]
Although ribosomal proteins are known for playing an essential role in ribosome assembly and protein translation, their ribosome-independent functions have also been greatly appreciated. Over the past decade, more than a dozen of ribosomal proteins have been found to activate the tumor suppressor p53 pathway in response to ribosomal stress. In addition,

The PDB and the ribosome [PDF]
This essay, which was written to commemorate the 50th anniversary of the Protein Data Bank, opens with some comments about the intentions of the scientists who pressed for its establishment and the nature of services it provides. It includes a brief account of the events that resulted in the determination of the crystal structure of the large ribosomal
