Overview
| Protein Change | Nucleotide Change | Mechanism | Organism | Resistance To | Database | Validation Status |
|---|---|---|---|---|---|---|
| V631F | - | Target modification, isoleucine--tRNA ligase IleS, single resistance variant | Staphylococcus aureus | MupirocinMUPIROCIN | Card DatabaseReference Gene CatalogResFinder DatabaseReslit | Confirmed |
| Y723H | - | - | Staphylococcus aureus, Escherichia coli | Vancomycin | Reslit | Candidate |
| I637V | - | - | Staphylococcus aureus | Mupirocin | Reslit | Candidate |
| V588F | V588 is located in a hydrophobic pocket that interacts directly with the fatty acid side chain of mupirocin, mutation of this residue causes steric repulsion to mupirocin, isoleucine--tRNA ligase IleS, single resistance variant, Target modification | Staphylococcus aureus | MupirocinMUPIROCIN | Card DatabaseReference Gene CatalogResFinder DatabaseReslit | Confirmed |
| K226T | - | K226T are on the outer surface adjacent to the tRNA molecule about 20 Å from the editing active site | Staphylococcus aureus | Mupirocin | Reslit | Candidate |
| V767D | - | V767D lies in the interior surface of the cylindrical central helical domain of the IleS, distal to the tRNA binding site | Staphylococcus aureus | Mupirocin | Reslit | Candidate |
| F227L | - | F227L are on the outer surface adjacent to the tRNA molecule about 20 Å from the editing active site | Staphylococcus aureus | Mupirocin | Reslit | Candidate |
