The penicillin-binding proteins: structure and role in peptidoglycan biosynthesis

TLDR
An overview of the content in PBPs of some bacteria is provided with an emphasis on comparing the biochemical properties of homologous PBPs (orthologues) belonging to different bacteria.
Abstract
Penicillin-binding proteins (PBPs) have been scrutinized for over 40 years. Recent structural information on PBPs together with the ongoing long-term biochemical experimental investigations, and results from more recent techniques such as protein localization by green fluorescent protein-fusion immunofluorescence or double-hybrid assay, have brought our understanding of the last stages of the peptidoglycan biosynthesis to an outstanding level that allows a broad outlook on the properties of these enzymes. Details are emerging regarding the interaction between the peptidoglycan-synthesizing PBPs and the peptidoglycan, their mesh net-like product that surrounds and protects bacteria. This review focuses on the detailed structure of PBPs and their implication in peptidoglycan synthesis, maturation and recycling. An overview of the content in PBPs of some bacteria is provided with an emphasis on comparing the biochemical properties of homologous PBPs (orthologues) belonging to different bacteria.

SurE is a trans-acting thioesterase cyclizing two distinct non-ribosomal peptides

TL;DR: SurE is a new, stand-alone thioesterase (TE) offloading the non-ribosomal peptide (NRP) assembly line found in surugamide biosynthesis and capable of cyclizing two structurally unrelated substrates derived from two different NRP assembly lines, highlighting the broad substrate tolerance of the SurE offloading cyclase.

Reconstitution of TCA cycle with DAOCS to engineer Escherichia coli into an efficient whole cell catalyst of penicillin G

TL;DR: The feasibility to redirect the TCA cycle to drive a desired enzyme reaction, and this strategy could be applied to other enzymes that catalyze T CA cycle-coupleable reactions, is demonstrated.

Promoting acid resistance and nisin yield of Lactococcus lactis F44 by genetically increasing D-Asp amidation level inside cell wall.

TL;DR: A novel strategy for enhancing nisin yield through cell wall remodeling is provided, which contributed to both continuous nisin synthesis and less nisin adsorption in acidic fermentation (dual enhancement).

Molecular Characterization of Equine Staphylococcus aureus Isolates Exhibiting Reduced Oxacillin Susceptibility.

TL;DR: Phenotypic resistance to penicillins, aminoglycosides, tetracyclines, fluoroquinolones and sulfamethoxazole/trimethoprim was observed in the respective isolates and β-lactamase activity was found to be associated with an inducible blaZ gene.

High-Throughput Screening for Novel Inhibitors of Neisseria gonorrhoeae Penicillin-Binding Protein 2

TL;DR: A FP-based assay is developed that uses fluorescence polarization (FP) to find novel inhibitors of penicillin-binding proteins (PBPs) and paves the way for more comprehensive high-throughput screening against highly resistant strains of N. gonorrhoeae.

Peptidoglycan structure and architecture

TL;DR: In several species examined, the fine structure of the peptidoglycan significantly varies with the growth conditions, and the different models for the architecture are discussed with respect to structural and physical parameters.

Growth of the Stress-Bearing and Shape-Maintaining Murein Sacculus of Escherichia coli

TL;DR: A model is presented that postulates that maintenance of bacterial shape is achieved by the enzyme complex copying the preexisting murein sacculus that plays the role of a template.
