Inhibition of Fructose-1,6-bisphosphatase by Aminoimidazole Carboxamide Ribotide Prevents Growth of Salmonella enterica purH Mutants on Glycerol [PDF]

, 2006
The enzyme fructose-1,6-bisphosphatase (FBP) is key regulatory point in gluconeogenesis. Mutants of Salmonella enterica lacking purH accumulate 5-amino-4-imidazole carboxamide ribotide (AICAR) and are unable to utilize glycerol as sole carbon and energy ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

A novel insight into ComE-mediated activation of gene expression in Streptococcus mutans

Microbiology Spectrum
Bacteria use two-component signal transduction systems (TCSs) to sense and respond to environmental changes. TCSs comprise a histidine kinase that senses environmental signals and a response regulator that regulates cognate promoters.

Identification of possible Ser/Thr/Tyr phosphorylation sites in the fungal histidine kinase CaNik1p by peptide array technique

Bulletin of Faculty of Pharmacy Cairo University, 2018
CaNik1p is a histidine kinase (HK) that is present in Candida albicans. It was found to be a target for antifungal activities on the hyperosmotic glycerol pathway.

Probing the nucleotide-binding activity of a redox sensor: two-component regulatory control in chloroplasts [PDF]

, 2016
Two-component signal transduction systems mediate adaptation to environmental changes in bacteria, plants, fungi, and protists. Each two-component system consists of a sensor histidine kinase and a response regu- lator. Chloroplast sensor kinase (CSK) is

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Recombinant Cytosolic Truncations of Histidine Kinases Retain Function for Targeted In Vitro Investigations

Microorganisms
Histidine kinases are an integral component of bacterial two-component systems (TCSs), playing a pivotal role in signal transduction pathways, resulting in both resistance and virulence. However, their inherent membrane-bound nature often results in poor
