mecC-type mecI

Ontology CARD's Antibiotic Resistance Ontology
Accession ARO:3005046
CARD Short NamemecC-type_mecI
DefinitionA mecC-type mecI repressor gene which mediates production of PBP2 by mecC. In methicillin-resistant Staphylococci possessing the mecC gene, mecI represses the expression of mecC thereby restoring or increasing susceptibility to methicillin and beta-lactam antibiotics.
AMR Gene FamilyPBP2-like beta-lactam resistant peptidoglycan transpeptidase, gene modulating beta-lactam resistance
Drug Classpenicillin beta-lactam, cephalosporin, carbapenem, monobactam
Resistance Mechanismantibiotic target replacement

Resistomes

Prevalence of mecC-type mecI 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): 200
