Analysis of Bacterial Proteins by 2DE
2009Two-dimensional gel electrophoresis (2DE) is a key analytical method for investigating bacterial -proteomes. The relatively simple genomes of many bacteria combined with only limited post--translational modifications of bacterial proteins mean that a significant proportion of the proteome is open to analysis by 2DE. The applications of 2DE in the field

The Bacterial RecA Protein as a Motor Protein
Annual Review of Microbiology, 2003▪ Abstract The bacterial RecA protein plays a central role in the repair of stalled replication forks, double-strand break repair, general recombination, induction of the SOS response, and SOS mutagenesis. The major activity of RecA in DNA metabolism is the promotion of DNA strand exchange reactions.

A bacterial dynamin-like protein
Nature, 2006Dynamins form a superfamily of large mechano-chemical GTPases that includes the classical dynamins and dynamin-like proteins (DLPs). They are found throughout the Eukarya, functioning in core cellular processes such as endocytosis and organelle division.

Analysis of bacterial biotin-proteins
Biochimica et Biophysica Acta (BBA) - Protein Structure, 1975The biotin-protein populations in several bacterial strains were analyzed by solubilization of [3H]biotin-labeled cells with sodium dodecylsulfate followed by electrophoresis on polyacrylamide gels containing the detergent. A variety of patterns of biotin-labeled polypeptide chains was seen, ranging from a single biotin-protein in Escherichia coli ...

Myristoylation of viral and bacterial proteins
Trends in Microbiology, 2004Abstract Myristoylation, the N-terminal attachment of a myristoyl lipid anchor to a glycine residue, can reversibly direct protein–membrane and protein–protein interactions. Apart from two entomopoxviruses, viruses and bacteria usually lack the enzyme N-myristoyltransferase (NMT) that is required for this modification, and their proteins are ...

Highly phosphorylated bacterial proteins
PROTEOMICS, 2004AbstractWe show in Gram‐negative and Gram‐positive bacteria the appearance of highly acidic proteins, which are highly phosphorylated. This group of proteins includes many cellular proteins, such as chaperones, biosynthetic, and metabolic enzymes. These proteins accumulate under stress conditions or under conditions, which overload the proteolytic ...

Cellular and Molecular Life Sciences, 2002
Members of a family of small cold-shock proteins (CSPs) are induced during bacterial cell response to a temperature decrease. Here we review available data about the structure, molecular properties, mechanism of induction and possible functions of CSPs.

Protein engineering with bacterial display
Current Opinion in Structural Biology, 2007Recent improvements in bacterial surface display systems coupled with efficient selection and screening strategies are propelling bacterial display systems to the forefront of peptide and protein engineering. The ability to analyze and screen very large protein libraries using cell-sorting instrumentation coupled with the ease of manipulating bacteria ...

Protein Quality Control in the Bacterial Periplasm
Annual Review of Microbiology, 2011Protein quality control involves sensing and treatment of defective or incomplete protein structures. Misfolded or mislocalized proteins trigger dedicated signal transduction cascades that upregulate the production of protein quality-control factors. Corresponding proteases and chaperones either degrade or repair damaged proteins, thereby reducing the

Cell penetration of bacterial protein toxins
Trends in Microbiology, 1995I mportant advances have been made recently in the study of cell penetration by bacterial protein toxins . I,* Many protein toxins from bacteria and plants have their effects in the cytosol of cells. Rather than reaching their targets directly through the plasma membrane, these toxins exploit the endocytotic pathway and enter the cytosol from ...
