Characterization of Mycobacterium avium cytoplasmic membrane proteins with an emphasis on the major cytoplasmic membrane protein
Proteins of the cytoplasmic membrane of Mycobacterium avium were investigated to identify those which were: (1)intrinsic or extrinsic, (2) attached to the cell wall, (3)surface accessible and (4) excreted. In addition sera containing anti-cytoplasmic membrane proteins were obtained and preliminary …

Interaction of Colicin Ia With Escherichia Coli: I. Mechanisms of Colicin Insensitivity. Ii. Inhibition of Colicin Binding by Phenolic Uncouplers
… of TonB strains are insensitive to colicin Ia, cytoplasmic membrane vesicles prepared from a TonB strain are sensitive to colicin-induced membrane depolarization. This finding shows that the TonB function is not required for channel formation and maintenance within the cytoplasmic membrane, but, …

The ultrastructure of a marine luminous bacterium
… were tetrads, cells in which ingrowth of the cytoplasmic membrane causes the contents to be divided up into four protoplasts within the cell wall. Small cytoplasmic spherules which arise from the cytoplasmic membrane were also seen to occur. The cell walls which were three-layered and typical …

The dual-targeted membrane assembly of the <i>Streptomyces coelicolor</i> Rieske protein
… for protein export across the bacterial cytoplasmic membrane - the general secretory (Sec) system and the twin-arginine translocation (Tat) system. Both translocases can also insert membrane proteins. The Sec machinery inserts multiple transmembrane domains into the cytoplasmic membrane …

Organization of the Streptococcal ExPortal and its Interaction with Cationic Antimicrobial Peptides
… once they have been translocated across the cytoplasmic membrane. <italic>S. pyogenes<italic/> and other Gram-positive organisms overcome this challenge by clustering the secretory translocons at a defined anionic lipid microdomain of the cytoplasmic membrane that is enriched for accessory …

Structure, function, and evolution of proline transport systems in Salmonella typhimurium
… energy utilization. Nutrient uptake across the cytoplasmic membrane is mediated by integral membrane proteins called permeases. The goal of this research was to understand the structure and function of the substrate binding site of proline permease and the evolution of a new proline transport …

Tales of Seduction and Betrayal: Host Genes Required for Assault of Salmonella by Bacteriophage P22
… step where phage DNA is translocated across the cytoplasmic membrane into the cell. Bacteria with mutations in any of these host factors required by the phage would gain resistance to infection by P22. Consequently, chemically mutagenized bacteria were exposed to a high multiplicity of a virulent …

Molecular genetic studies of the cytochrome o terminal oxidase complex in Escherichia coli
… of ubiquinol-8 to ubiquinone-8 within the cytoplasmic membrane and the concomitant reduction of O$\sb2$ to H$\sb2$O. Cytochrome $o$ oxidase has been purified and shown to contain four subunits on SDS-PAGE gels. The cloning of the $cyo$ operon makes it possible to address a number of …

NOVEL ASPECTS OF ULTRASTRUCTURE IN TWO SPECIES OF CYANOBACTERIA (AGMENELLUM QUADRUPLICATUM, MASTIGOCLADUS LAMINOSUS)
… photosynthetic thylakoid system consisted of 3-6 membrane sheets that traversed and were parallel to the long axis of the cell. These sheets were arranged as an anastomosing network of concentric shells. They coalesced and approached the cytoplasmic membrane at three peripheral loci along the …

Action at a distance for specific repression of the glpD and glpTQ genes, and organization of the glpEGR genes of Escherichia coli K-12
… (glycerol-P) dehydrogenase is a cytoplasmic membrane-associated respiratory enzyme encoded by the g/pD gene of Escherichia coli. The divergently transcribed glpACB and glpTQ operons encode the subunits of the anaerobic glycerol-P dehydrogenase, glycerol-P transporter, and …

Construction of an efficient secretion system for recombinant proteins in Bacillus subtilis
All proteins being translocated through the cytoplasmic membrane of bacteria cells as well as some proteins that are inserted into the cytoplasmic membrane contain a signal sequence at their N-terminus that is recognized by and targeted to the translocation machinery. Three translocation pathways …

Analysis of the topology of the cytochrome d terminal oxidase complex of Escherichia coli by genetic methods
… of subunit I and associates with the cytoplasmic membrane. It does not appear to have any of the cytochrome components associated with it under these conditions. The plasmid expressing subunit II complements another plasmid expressing subunit I, restoring oxidase activity. The …

Genetic relatedness of the family Rhodospirillaceae: Genome plasticity, chromosome heterogeneity, and chalcogenic oxyanion reductase activity in Rhodobacter sphaeroides
… and resulted in elemental deposition in the cytoplasmic membrane, and concomitant H$\sb2$ evolution during photoheterotrophic growth in the presence of these oxyanions. Based on the analysis of TnphoA-derived mutants, the periplasmic-localized dimethyl sulfoxide/trimethylamine-N-oxide …

Identification of binding protein with kinesin18B
… Most kinesins move cargoes outwards toward the cytoplasmic membrane. Members of the kinesin family have been implicated in vesicle and organelle transport, spindle and chromosome motility during meiosis and mitosis, microtubule destabilization, and flagellar and ciliary function. In the present …

Optimisation of the preservation of microbial cell banks for enhanced fermentation process performance
… as a cell having an intact and fully polarised cytoplasmic membrane. It was found that the concentration and type of cryopreservant used had a significant effect on microbial cell physiology and population heterogeneity during resuscitation recovery immediately after thawing. Cell banks prepared …

Characterization of two novel proteins containing the rhodanese homology domain: YgaP and YbbB of Escherichia coli
… into a vector that directed overexpression of a membrane-associated rhodanese activity. The cellular location of YgaP was determined by using sucrose density layer ultracentrifugation. YgaP and rhodanese activity co-sedimented with the cytoplasmic membrane marker D-lactate dehydrogenase, and was …

Lysin Based Antimicrobial Peptides Against Acinetobacter Baumannii
… domain with a likely role in promoting outer membrane penetration. In the current study, we show that the C-terminal amino acids 108-138 of phage lysin PlyF307, named P307, alone was sufficient to kill A. baumannii (>3-logs). Furthermore, P307 could be engineered for improved activity, the …

Studies on the outer membrane of Pseudomonas aeruginosa and associated resistance properties
… PAO1 alterations in the fatty acids of the cytoplasmic membrane, increase in expression of OprG, decrease in susceptibility to EDTA as an outer membrane permeabilising agent and an increase in negativity of the cell surface charge were observed as cells became more resistant to BKC. In …
