A Single‐Nucleotide Substitution Generates a de Novo Promoter That Activates a Latent Metabolic Bypass in Escherichia coli

Molecular Microbiology, EarlyView.
A chromosomal mutation allows bypass of deletion of the Escherichia coli fabH gene. The bypass results from creation of a new promoter that drives increased madA transcription, resulting in increased synthesis of acetyl‐acyl carrier protein by decarboxylation of malonyl‐acyl carrier protein.

The ComEA/ComEC Operon is Critical for Nitrosative Stress Tolerance by an Oral Commensal

Molecular Oral Microbiology, EarlyView.
ABSTRACT Oral commensal streptococci play a large role in mediating microbial homeostasis. Our prior work has demonstrated that hydrogen peroxide (H2O2) produced by oral commensal streptococci can react with salivary nitrite (NO2) and generate peroxynitrite (ONOO−), a potent antimicrobial.

Novel Amino Acid Changes Increase Phosphoenolpyruvate Carboxylase Output in planta

Plant, Cell &Environment, EarlyView.
ABSTRACT Characterization of previously reported Arabidopsis mutants with increased aluminum (Al) resistance (alr) resulting from greater release of Al‐chelating malate identified three unique amino acid substitutions that each impacts PHOSPHOENOLPYRUVATE CARBOXYLASE 1, a key anaplerotic carbon fixation enzyme.

The effects of far‐UVC irradiation on the presence and concentration of ESKAPEE pathogens on hospital surfaces: Study protocol for a multi‐site, double‐blinded randomized controlled trial in La Paz, Bolivia

Photochemistry and Photobiology, EarlyView.
The protocol of a multi‐site, double‐blinded, clustered randomized controlled trial (cRCT) with a binary outcome of the presence of viable presumptive ESKAPEE pathogens on surfaces in and around hospital sinks is to be implemented in two Bolivian hospitals.
