Resistance Mechanisms to Antimicrobial Peptides in Gram-Positive Bacteria
With the alarming increase of infections caused by pathogenic multidrug-resistant bacteria over the last decades, antimicrobial peptides (AMPs) have been investigated as a potential treatment for those infections, directly through their lytic effect or ...

Mismatch repair in Gram-positive bacteria [PDF]
DNA mismatch repair (MMR) is responsible for correcting errors formed during DNA replication. DNA polymerase errors include base mismatches and extra helical nucleotides referred to as insertion and deletion loops. In bacteria, MMR increases the fidelity of the chromosomal DNA replication pathway approximately 100-fold.

The cannabinoid cannabidiol (CBD) is characterised in this study as a helper compound against resistant bacteria. CBD potentiates the effect of bacitracin (BAC) against Gram-positive bacteria (Staphylococcus species, Listeria monocytogenes, and ...

Sortase enzymes in Gram‐positive bacteria [PDF]
SummaryIn Gram‐positive bacteria proteins are displayed on the cell surface using sortase enzymes. These cysteine transpeptidases join proteins bearing an appropriate sorting signal to strategically positioned amino groups on the cell surface. Working alone, or in concert with other enzymes, sortases either attach proteins to the cross‐bridge peptide ...

Small proteins in Gram-positive bacteria
Abstract Small proteins comprising less than 100 amino acids have been often ignored in bacterial genome annotations. About 10 years ago, focused efforts started to investigate whole peptidomes, which resulted in the discovery of a multitude of small proteins, but only a number of them have been characterized in detail.

Presence of squalene in gram-positive bacteria [PDF]
The presence of the isoprenoid squalene, synthesized de novo, was demonstrated in 64 out of 73 strains of gram-positive bacteria by thin-layer chromatography. This observation was confirmed by gas-liquid chromatography, chemical reactivity, incorporation of radiolabeled precursor, and by gas chromatography mass spectroscopy of thin-layer chromatography-

Mobile Oxazolidinone Resistance Genes in Gram-Positive and Gram-Negative Bacteria
Seven mobile oxazolidinone resistance genes, including cfr, cfr(B), cfr(C), cfr(D), cfr(E), optrA, and poxtA, have been identified to date. The cfr genes code for 23S rRNA methylases, which confer a multiresistance phenotype that includes resistance to ...
