Dynamical Behavior of β-Lactamases and Penicillin- Binding Proteins in Different Functional States and Its Potential Role in Evolution [PDF]
Entropy, 2019 β-Lactamases are enzymes produced by bacteria to hydrolyze β-lactam-based antibiotics, and pose serious threat to public health through related antibiotic resistance.

Frontiers in Microbiology, 2023 IntroductionFor Streptococcus pneumoniae, β-lactam susceptibility can be predicted from the amino acid sequence of the penicillin-binding proteins PBP1a, PBP2b, and PBP2x.

New noncovalent inhibitors of penicillin-binding proteins from penicillin-resistant bacteria. [PDF]
PLoS ONE, 2011 BACKGROUND: Penicillin-binding proteins (PBPs) are well known and validated targets for antibacterial therapy. The most important clinically used inhibitors of PBPs β-lactams inhibit transpeptidase activity of PBPs by forming a covalent penicilloyl ...

International Journal of Infectious Diseases, 2022 Objectives: Nonencapsulated Streptococcus pneumoniae (NESp) is emerging after the introduction of pneumococcal conjugate vaccines (PCVs). This study aimed to elucidate the genetic characteristics of penicillin-binding proteins (PBPs; PBP1a, 2b, and 2x ...

Penicillin‐Binding Protein Imaging Probes [PDF]
Current Protocols in Chemical Biology, 2013 ABSTRACTPenicillin‐binding proteins (PBPs) are membrane‐associated proteins involved in the biosynthesis of peptidoglycan (PG), the main component of bacterial cell walls. These proteins were discovered and named for their affinity to bind the β‐lactam antibiotic penicillin.

Penicillin-binding proteins of bdellovibrios [PDF]
Journal of Bacteriology, 1988 We examined the predacious gram-negative bacterium Bdellovibrio bacteriovorous 109J and free-living strains 109J-A1 and 109J-KA1 derived therefrom for penicillin-binding proteins (PBPs). We compared their PBPs with those of the host bacterium, Escherichia coli, and with those of a facultatively predacious bdellovibrio, B. stolpii UKi2, grown axenically.

Penicillin-binding proteins in bacteria [PDF]
Antimicrobial Agents and Chemotherapy, 1980 The penicilllin-binding proteins (PBPs) of several gram-positive and gram-negative bacteria have been examined. The results indicate that: (i) PBPs are membrane proteins with molecular weights ranging from 40,000 to 120,000. When extracted with Triton X-100 from sonicated cells, they appear to fall into two patterns: one found in rods and the other in ...

Kinetics of penicillin binding to penicillin-binding proteins of Staphylococcus aureus [PDF]
Biochemical Journal, 1994 Reduced affinity of penicillin-binding proteins (PBPs) for binding penicillin has been proposed as a mechanism of beta-lactam antibiotic resistance in staphylococci. Penicillin binding by PBPs of three penicillin-susceptible and two penicillin-resistant strains of Staphylococcus aureus was studied in kinetic assays to determine rate constants, drug ...

Construction and Activity Testing of a Modular Fusion Peptide against Enterococcus faecalis
Antibiotics, 2023 The emergence of antibiotic resistance in enterococci is a great concern encountered worldwide. Almost all enterococci exhibit significant levels of resistance to penicillin, ampicillin, semi-synthetic penicillin and most cephalosporins, primarily due to
