RNA processing in prokaryotic cells

BioEssays, 1993
AbstractRNA processing in Escherichia coli and some of its phages is reviewed here, with primary emphasis on rRNA and tRNA processing. Three enzymes, RNase III, RNase E and RNase P are responsible for most of the primary endonucleolytic RNA processing events. The first two are proteins, while RNase P is a ribozyme.

In-Cell NMR of Intrinsically Disordered Proteins in Prokaryotic Cells

Methods in molecular biology, 2012
In-cell NMR, i.e., the acquisition of heteronuclear multidimensional NMR of biomacromolecules inside living cells, is, to our knowledge, the only method for investigating the three-dimensional structure and dynamics of proteins at atomic detail in the intracellular environment.

Cell Division in Prokaryotes and Eukaryotes

2022
This chapter discusses cell division in prokaryotes and eukaryotes. Life on Earth depends on cell division and the transfer of genetic information which triggers the propagation and evolution of species. Unlike the reproduction of eukaryotes, prokaryotes adopt asexual reproduction strategies such as binary fission, budding, or fragmentation.

Cytology and Morphogenesis of the Prokaryotic Cell [PDF]

, 1993
The peptidoglycan sacculus of a bacterial cell which is located at the outside of the cytoplasmic membrane is considered to be the load-bearing structure of Gram-positive and Gram-negative eubacteria. Numerous reports over the last few years based on electron microscopic analysis of freeze-substituted thin-sectioned cells and pulsed addition of ...

Programmed Cell Death in Prokaryotes [PDF]

Critical Reviews in Microbiology, 1997
Programmed cell death (PCD), also referred to as apoptosis, is a cellular "suicide" mechanism, based on information from its own internal metabolism, environment, developmental history, and genome. This system was described in eukaryotes continuously along evolution, through amoebae, nematodes, insects, and animals.

Effects of benzyladenine on prokaryotic and eukaryotic cells

Mutation Research Letters, 1992
Comparative studies of the effect of benzyladenine (BA) on the yeast Saccharomyces cerevisiae, the bacterium Salmonella typhimurium, the shallot Allium ascalonicum and Chinese hamster fibroblast cells were performed. The tested substance had no mutagenic activity on yeast, bacteria and cultured fibroblast cells.

Single-cell model of prokaryotic cell cycle

Journal of Theoretical Biology, 2014
One of the recognized prokaryotic cell cycle theories is Cooper-Helmstetter (CH) theory which relates start of DNA replication to particular (initiation) cell mass, cell growth and division. Different aspects of this theory have been extensively studied in the past. In the present study CH theory was applied at single cell level.

Evaluation of Prokaryotic and Eukaryotic Cell

Asian Journal of Pharmaceutical Research, 2021
In the “ecosystems-first” approach to the origins of life, networks of noncovalent assemblies of molecules (composomes), rather than individual protocells, evolved under the constraints of molecular complementarity. Composomes evolved into the hyperstructures of modern bacteria.

Fluorescence turn-on detection of Sn2+ in live eukaryotic and prokaryotic cells.

In Analysis, 2014
Sn(2+) is usually added to toothpaste to prevent dental plaque and oral disease. However, studies of its physiological role and bacteriostatic mechanism are restricted by the lack of versatile Sn(2+) detection methods applicable to live cells, including ...
