| Synonym(s) | NiCoT NicT Rv2856 |
| CARD Short Name | Rv2856 |
| Definition | Ectopic expression of NiCoT in Escherichia coli CS109 resulted in the increase of intracellular nickel uptake with enhanced tolerance towards several antibiotics when NiCoT was overexpressed in E. coli and Mycobacterium smegmatis. The presence of a sub-inhibitory dose of nickel resulted in the manifestation of low-level tolerance towards these drugs. |
| AMR Gene Family | metal transporters with antibiotic efflux |
| Drug Class | isoniazid-like antibiotic, fluoroquinolone antibiotic, aminoglycoside antibiotic |
| Resistance Mechanism | antibiotic efflux |

Prevalence of putative nickel/cobalt transporter among the sequenced genomes, plasmids, and whole-genome shotgun assemblies available at NCBI or IslandViewer for 413 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).

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): 700
