Effect of Azasteroids on Gram-Positive Bacteria
Journal of Bacteriology, 1967A group of nitrogen-containing steroids closely related in structure was screened for antibacterial activity, by use of Bacillus subtilis and Sarcina lutea as the test organisms. The most active compounds were cholesterol derivatives containing a tertiary or quaternary nitrogen in, or ...

Membrane transitions in Gram-positive bacteria
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1971Abstract Intact cells, membranes, and aqueous dispersion of lipids of Micrococcus lysodeikticus undergo a reversible thermotropic transition detectable by differential scanning calorimetry. The phenomenon is suggested to be a “melt” of fatty acid chains within lipid bilayers.

Innate sensors for Gram-positive bacteria
Current Opinion in Immunology, 2003More than half of invasive bacterial infections are Gram-positive in origin. This class of bacteria has neither endotoxins nor an outer membrane, yet it generates some of the most powerful inflammatory responses known in medicine. Some recent seminal studies go a long way toward settling the controversies that surround the process by which Gram ...

Selenoproteins in Archaea and Gram-positive bacteria
Biochimica et Biophysica Acta (BBA) - General Subjects, 2009Selenium is an essential trace element for many organisms by serving important catalytic roles in the form of the 21st co-translationally inserted amino acid selenocysteine. It is mostly found in redox-active proteins in members of all three domains of life and analysis of the ever-increasing number of genome sequences has facilitated identification of

Protein secretion in Gram-positive bacteria
Journal of Biotechnology, 1992Gram-positive bacteria often secrete large amounts of proteins into the surrounding medium. This feature makes them attractive as hosts for the industrial production of extracellular enzymes. Compared to Escherichia coli, relatively little is known about the mechanism of protein secretion in these organisms.

Infections by Gram-positive bacteria: an overview
Journal of Antimicrobial Chemotherapy, 1988Staphylococcus aureus, which has exceptional ability to cause disease in man, has responded to the introductions of antimicrobial agents by the selection and emergence of antibiotic-resistant strains. There have been cyclical changes in the prevalence of these strains in nosocomial infections.

Gram-Positive Bacteria in the Marine Environment
2006The classicGram-positive bacteria used as fecal contamination indicators are enterococci (fecal streptococci) and clostridia. However, many other Gram-positive bacteria of human origin or potentially human pathogens, such as staphylococci, listeriae, mycobacteria, bifidobacteria, may be present in seawater.

Pilus Assembly in Gram-Positive Bacteria
2015Pili of Gram-positive bacteria are unique structures on the bacterial surface, assembled from covalently linked polypeptide subunits. Pilus assembly proceeds by transpeptidation reactions catalyzed by sortases, followed by covalent anchoring of the filament in the peptidoglycan layer.

Protein Secretion in Gram-Positive Bacteria
2003Studies on protein secretion in Gram-positive bacteria have become of particular importance since many species are of great commercial value and medical interest. Several Gram-positive bacteria have been applied successfully for cost-effective industrial production of enzymes since, due to the absence of an outer membrane, proteins are secreted ...
