ABSTRACT Persistent infection by Staphylococcus aureus has been linked to the bacterial stringent response (SR), a conserved stress response pathway regulated by the Rel protein. Rel synthesizes (p)ppGpp “alarmones” in response to amino acid star

ABSTRACT Feedback mechanisms are fundamental to the control of physiological responses. One important example in gene regulation, termed negative autoregulation (NAR), occurs when a transcription factor (TF) inhibits its own production through transc

Many antibiotics, either directly or indirectly, cause DNA damage thereby activating the bacterial DNA damage (SOS) response. SOS activation results in expression of genes involved in DNA repair and mutagenesis, and the regulation of the SOS response

ABSTRACT The bacterial SOS response is a DNA damage repair network that is strongly implicated in both survival and acquired drug resistance under antimicrobial stress. The two SOS regulators, LexA and RecA, have therefore emerged as potential target

In this issue of Structure, Maso et al. (2022) discover nanobodies that inhibit the SOS response of Escherichia coli by targeting the LexA repressor-protease. High-resolution structures of the novel LexA-nanobody complexes reveal they function by sta

Severe infections caused by methicillin-resistant Staphylococcus aureus (MRSA) are often complicated by persistent bacteremia (PB) despite active antibiotic therapy. Antibiotic resistance rarely contributes to MRSA-PB, suggesting an important role fo

Microbes are constantly evolving. Laboratory studies of bacterial evolution increase our understanding of evolutionary dynamics, identify adaptive changes, and answer important questions that impact human health. During bacterial infections in humans

The bacterial DNA damage response pathway (SOS response) is composed of a network of genes regulated by a single transcriptional repressor, LexA. The lexA promoter, itself, contains two LexA operators, enabling negative feedback. In Escherichia coli,

The bacterial SOS response to DNA damage induces an error-prone repair program that is mutagenic. In Escherichia coli, SOS-induced mutations are caused by the translesion synthesis (TLS) activity of two error-prone polymerases (EPPs), Pol IV and Pol

Background Persistent MRSA bacteremia is common with high morbidity and mortality despite appropriate antibiotics. Persistent infections are associated with antibiotic tolerance and can arise from perturbations in cellular pathways. We performed whol
