positive bacterial genomes has grouped sortases into four different classes (A to D)[5]. Sortase A (SrtA) is present in almost all strains belonging to low GC% Gram-positive species and plays an important role in different stages of the pathogenic process in many Gram-positive bacteria[6]...
Bacillus subtilisis the best-characterized member of the Gram-positive bacteria. Its genome of 4,214,810 base pairs comprises 4,100 protein-coding genes. Of these protein-coding genes, 53% are represented once, while a quarter of the genome corresponds to several gene families that have been ...
Many of these genes are associated with virulence genes identified in patho- genic Gram-positive bacteria, suggesting that such virulence factors are transmitted horizontally among bacteria at a much higher frequency than previously thought. If we include these A þ T-rich regions as possible ...

In this study, chemically synthesized tick defensin was used to further investigate the activity spectrum and mode of action of natural tick defensin. Synthetic tick defensin showed antibacterial activity against many Gram-positive bacteria but not Gram-negative bacteria and low hemolytic activity, ...
Many studies have proven the ability of plant extracts, especially the volatile oils in aromatic or medicinal plants such as Ginger and Thyme, to inhibit or kill negative bacteria such as Pseudomonas aeruginosa and Gram-positive bacteria such as Staphylococcus aureus,...
In this study, we address the importance of accessibility to PG in PGRP-mediated recognition of whole bacteria in more general terms. In addition to S. aureus as the Lys-type representative, we used B. subtilis as the DAP-type model. We found that in a hemolymph-like buffer, both PGRPs...
Chaperone/usher pathway In many Gram-negative bacteria, the biogenesis of P pili, which are encoded by the pap operon, occurs by the chaperone/usher pathway. In this system, PapD binds to, and caps, the pilus-subunit surface, preventing premature aggregation in the periplasm. This chaperone–...
Many antibiotics lack activity against Gram-negative bacteria because they cannot permeate the outer membrane or suffer from efflux and, in the case of β-lactams, are degraded by β-lactamases. Herein, we describe the synthesis and studies of a dual drug conjugate (1) of a siderophore linked...
