Microarray experiments were preformed comparing the effect of sub-inhibitory concentrations of ciprofloxacin on five independent cultures of PAO1 and the PAO1 Lon mutant
ORGANISM(S): Pseudomonas aeruginosa PAO1 
The bacterial Lon protease participates in a variety of biological processes. In Pseudomonas syringae, mutation of lon is known to activate hrpL and a few hrpL-regulated genes in the rich medium. The elevated expression of hrpL and hrpL-regulated genes results from of increased stability of HrpR, th...

Using Mycoplasma pneumoniae as a model organism, we conditionally depleted the two essential ATP-dependent proteases (Lon and FtsH) of this bacterium, by engineering three strains carrying a Lon and/or FtsH inducible expression locus. An integrative comparative study combining label-free shotgun pro...

With this analysis we aim to identify proteins that are substrates of LarA-activated Lon protease in Caulobacter crescentus. We will compare samples of wild type cells either harboring an empty vector (vector control, VC) or overexpressing 3xFLAG-tagged LarA (F-LarA). Based on our previous data we h...

We aim to identify potential substrates of the Lon protease in P. aeruginosa. Samples with the lon protease overexpressed or deleted were compared to the wild type to observe the proteins whose steady-state levels changed with change in Lon levels. We used spectinomycin to inhibit protein synthesis ...

Pseudomonas syringae uses HrpRSL to regulate the expression of type III secretion system (T3SS) genes and bacterial virulence. However, the molecular mechanism and the regulons of HrpRSL have yet to be fully elucidated. Here, we performed chromatin immunoprecipitation followed by high-throughput DNA...

Lon protease is known to regulate various transcriptional regulators in other bacterial organisms. To understand whether lon protease is involved in transcriptional changes in Vibrio cholerae, wholel-genome level transcriptional profiling was performed using custom microarrays. Transcriptomes of lon...
