Pseudomonas aeruginosa CpxR

Accession ARO:3004054
CARD Short NamePaer_CpxR
DefinitionCpxR is directly involved in activation of expression of RND efflux pump MexAB-OprM in P. aeruginosa. CpxR is required to enhance mexAB-oprM expression and drug resistance, in the absence of repressor MexR.
AMR Gene Familyresistance-nodulation-cell division (RND) antibiotic efflux pump
Drug Classpeptide antibiotic, sulfonamide antibiotic, diaminopyrimidine antibiotic, aminocoumarin antibiotic, penicillin beta-lactam, cephalosporin, aminoglycoside antibiotic, phenicol antibiotic, tetracycline antibiotic, carbapenem, monobactam, fluoroquinolone antibiotic, macrolide antibiotic
Resistance Mechanismantibiotic efflux
Efflux Componentefflux pump complex or subunit conferring antibiotic resistance
Efflux Regulatorprotein(s) and two-component regulatory system modulating antibiotic efflux
Resistomes with Perfect MatchesPseudomonas aeruginosag+p+wgs, Pseudomonas fluorescensg
Resistomes with Sequence VariantsPseudomonas aeruginosag+p+wgs, Pseudomonas fluorescensg

Resistomes

Prevalence of Pseudomonas aeruginosa CpxR among the sequenced genomes, plasmids, and whole-genome shotgun assemblies available at NCBI or IslandViewer for 414 important pathogens (see methodological details and complete list of analyzed pathogens). Values reflect percentage of genomes, plasmids, genome islands, or whole-genome shotgun assemblies that have at least one hit to the AMR detection model. Default view includes percentages calculated based on Perfect plus Strict RGI hits. Select the checkbox to view percentages based on only Perfect matches to AMR reference sequences curated in CARD (note: this excludes resistance via mutation as references in protein variant models are often wild-type, sensitive sequences).

Detection Models

Model Type: protein homolog model

Model Definition: Protein Homolog Models (PHM) detect protein sequences based on their similarity to a curated reference sequence, using curated BLASTP bitscore cut-offs. Protein Homolog Models apply to all genes that confer resistance through their presence in an organism, such as the presence of a beta-lactamase gene on a plasmid. PHMs include a reference sequence and a bitscore cut-off for detection using BLASTP. A Perfect RGI match is 100% identical to the reference protein sequence along its entire length, a Strict RGI match is not identical but the bit-score of the matched sequence is greater than the curated BLASTP bit-score cutoff, Loose RGI matches have a bit-score less than the curated BLASTP bit-score cut-off.

Bit-score Cut-off (blastP): 400
