- Frontiers | Antibiotic action and resistance: updated review of mechanisms, spread . . .
The mechanisms underlying the efficacy of antibiotics involve four distinct modes of action (Kaur Sodhi and Singh, 2022), including inhibition of DNA replication (Fàbrega et al , 2009), protein biosynthesis (Tenson, Lovmar, and Ehrenberg, 2003), cell wall biosynthesis (Cho, Uehara, and Bernhardt, 2014), and folic acid metabolism
- Penicillin Binding Proteins: key players in bacterial cell cycle and drug resistance . . .
Bacterial cell division and daughter cell formation are complex mechanisms whose details are orchestrated by at least a dozen different proteins Penicillin-binding proteins (PBPs), membrane-associated macromolecules which play key roles in the cell wall synthesis process, have been exploited for over 70 years as the targets of the
- Membrane Microdomain Disassembly Inhibits MRSA Antibiotic Resistance - Cell Press
This disables penicillin resistance in MRSA in a murine infection model, resulting in MRSA infections susceptible to penicillin antibiotic treatments This study shows that bacterial cells organize sophisticated programs for membrane compartmentalization and defines an innovative strategy to overcome MRSA antibiotic resistance and
- Antibiotic Resistance and the MRSA Problem - Microbiology Spectrum
Penicillin-binding protein 2 is essential for expression of high-level vancomycin resistance and cell wall synthesis in vancomycin-resistant Staphylococcus aureus carrying the enterococcal vanA gene complex
- Bacterial infections: Antimicrobial mechanism of action and bacterial resistance . . .
The antibiotic mode of mechanism includes inhibition of the cell wall by penicillin in preventing the bacteria from synthesizing peptidoglycan; protein synthesis by metronidazole through dispersion of the drug into the organism; nucleic acid synthesis by quinolone promoting cleavage of bacterial DNA in the DNA–enzyme complexes; and
- Penicillin’s Impact on Bacterial Cell Wall Synthesis
Explore how penicillin disrupts bacterial cell wall synthesis and the mechanisms behind its effectiveness and resistance Penicillin, a groundbreaking antibiotic discovered by Alexander Fleming in 1928, has revolutionized the treatment of bacterial infections
- Penicillin-binding proteins: the master builders and breakers of bacterial cell walls . . .
The β-Lactam target membrane-associated penicillin-binding protein (PBPs) that are involved in the synthesis and recycling of peptidoglycan, a structural component of both gram-positive and gram-negative bacterial cell walls β-lactam binding to PBP initiates their bactericidal activity by disrupting peptidoglycan synthesis and
- Mechanisms of Antimicrobial Resistance in Bacteria
Mechanisms include interference with cell wall synthesis (e g , β-lactams and glycopeptide agents), inhibition of protein synthesis (macrolides and tetracyclines), interference with nucleic acid synthesis (fluoroquinolones and rifampin), inhibition of a metabolic pathway (trimethoprim-sulfamethoxazole), and disruption of bacterial
- Penicillin-Binding Proteins: Diversity and Resistance Mechanisms
Penicillin-binding proteins (PBPs) are integral to the effectiveness of antibiotics, serving as key facilitators in bacterial cell wall synthesis The importance of PBPs lies not only in their biological role but also in their involvement in antibiotic resistance, a growing global health concern
- Antibiotic resistance: A key microbial survival mechanism that . . . - ScienceDirect
(A) Antibiotic resistance is evidenced through five general mechanisms: (A) Decreased permeability: the physical-chemical barriers provided by the outer membrane and metabolite-gating porins allow for controlled entry of molecules into the cell, preventing penetration of antibiotics
