1. Novel RelA-SpoT Homolog toxin-antitoxin systems that inhibit bacterial growth through production of toxic alarmone ppApp
Abstract : The stress alarmone nucleotides guanosine pentaphosphate (pppGpp) and tetraphosphate (ppGpp), collectively known as (p)ppGpp, are the molecular mediators of the bacterial stringent response — a bacterial stress response implicated in virulence, antibiotic tolerance and biofilm formation. At high concentrations, (p)ppGpp halts bacterial growth, inhibits protein synthesis and rewires transcription and metabolism. READ MORE

2. Bioinformatics, evolution and revolution in our understanding of toxin-antitoxin systems
Abstract : Bacteria experience a wide range of natural challenges during their life cycles, to which they must respond and adapt to live. Under stressed conditions such as amino acid starvation, bacteria slow down their growth mechanism by producing small alarmone nucleotides guanosine pentaphosphate (pppGpp) and tetraphosphate (ppGpp), collectively referred to as (p)ppGpp. READ MORE
