Image-based dynamic phenotyping reveals genetic determinants of filamentation-mediated beta-lactam tolerance [PDF]
, 2020 Antibiotic tolerance characterized by slow killing of bacteria in response to a drug can lead to treatment failure and promote the emergence of resistance.

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

Facilitation of penicillin haptenation to serum proteins. [PDF]
, 1993 Traditionally, penicillin binding to serum proteins was believed to be a passive chemical process; however, it appears to be facilitated by serum factors.

Classification of Beta-lactamases and penicillin binding proteins using ligand-centric network models. [PDF]
PLoS ONE, 2015 β-lactamase mediated antibiotic resistance is an important health issue and the discovery of new β-lactam type antibiotics or β-lactamase inhibitors is an area of intense research.

mBio, 2022 Bacterial cell division is a complex process requiring the coordination of multiple components to allow the appropriate spatial and temporal control of septum formation and cell scission. Peptidoglycan (PG) is the major structural component of the septum,

Gut Pathogens, 2009 While seven penicillin-binding proteins (PBPs) or PBP-like proteins have been identified either by radiolabelled penicillin binding studies or genomic analysis, only PBP3 has been considered of interest for Beta-lactams activity against Listeria ...

A CozE Homolog Contributes to Cell Size Homeostasis of
mBio, 2020 Control of peptidoglycan assembly is critical to maintain bacterial cell size and morphology. Penicillin-binding proteins (PBPs) are crucial enzymes for the polymerization of the glycan strand and/or their cross-linking via peptide branches.

mBio, 2023 The peptidoglycan (PG) layer protects bacteria from osmotic lysis and defines their shape. The class A penicillin-binding proteins (aPBPs) are PG synthases that possess both glycan polymerization and crosslinking activities needed for PG biogenesis.

Reprogramming Hansenula polymorpha for penicillin production: expression of the Penicillium chrysogenum pcl gene [PDF]
, 2007 We aim to introduce the penicillin biosynthetic pathway into the methylotrophic yeast Hansenula polymorpha. To allow simultaneous expression of the multiple genes of the penicillin biosynthetic pathway, additional markers were required.
