Detection of Protein–Protein Interactions in Escherichia coli With Single Molecule Sensitivity
Advanced Science, Volume 13, Issue 37, 3 July 2026.This article describes a regulatory circuit in Escherichia coli able to detect protein–protein interactions with exquisite sensitivity. The interaction between two hybrid proteins fused to Bordetella pertussis adenylate cyclase and its activator calmodulin triggers a potent cyclic AMP signaling cascade.

In vivo cell division gene product interactions in Escherichia coli K-12 [PDF]
, 1987 Overexpression of plasmid-coded PBP 3 was analyzed in strains harboring ftsA, ftsH, pbpB (ftsI), ftsQ, ftsZ, or recA441 (Tif) mutations. Higher cellular levels of PBP 3, the pbpB gene product, could not restore septum formation of ftsA, ftsQ, ftsZ, and ...

mLife, Volume 5, Issue 3, Page 325-338, June 2026.Abstract The elongasome, or the Rod complex, orchestrates lateral peptidoglycan (PG) synthesis in many rod‐shaped bacteria. It consists of the actin‐like protein MreB, the PG synthase RodA‐PBP2 complex, as well as MreCD and RodZ. Although the loss or disruption of any elongasome component results in a loss of rod shape, previous studies found that a ...

A novel PBP3 substitution in Haemophilus influenzae confers reduced aminopenicillin susceptibility
BMC Microbiology, 2018 Background Identification and characterization of non-typeable Haemophilus influenzae (NTHi) with reduced susceptibility to β-lactam antibiotics due to mutations in penicillin binding protein 3 (PBP3) is a clinical challenge. We analyzed a blood isolate,

APMIS, Volume 134, Issue 4, April 2026.ABSTRACT The emergence of cefotaxime‐resistant Haemophilus influenzae (CRHI) in Norway during the 2000s coincided with increased use of oral aminopenicillins and parenteral third‐generation cephalosporins. This study examined associations between beta‐lactam consumption and CRHI incidence. Surveillance data on antibiotic usage across Norwegian regions (

Cefuroxime resistance in non-β-lactamase Haemophilus influenzae is linked to mutations in ftsI [PDF]
, 2003 The penicillin binding protein (PBP) genes dacA, dacB and ftsI from 14 cefuroxime-resistant (CXM(R)) isolates and three clinical isolates with low CXM MIC for non-beta-lactamase-producing Haemophilus influenzae type b were molecularly characterized.

SanA Plays a Role in Peptidoglycan Integrity in Escherichia coli
Molecular Microbiology, Volume 125, Issue 4, Page 343-357, April 2026.SanA is a novel regulator of peptidoglycan synthesis, potentially through functional interplay with PBP1B‐dependent pathways. ABSTRACT Peptidoglycan synthesis and degradation are both essential for bacterial growth, and damaged peptidoglycan must be continuously repaired. In Escherichia coli, peptidoglycan required for cell elongation is synthesized by

Contribution of ROB-1 and PBP3 mutations to the resistance phenotype of a β-lactamase-positive amoxicillin/clavulanic acid-resistant Haemophilus influenzae carrying plasmid pB1000 in Italy. [PDF]
, 2011 OBJECTIVES: plasmid pB1000 bearing bla(ROB-1) is responsible for high-level β-lactam resistance in Haemophilus influenzae as well as in Pasteurella multocida and Haemophilus parasuis isolates from Spain.
