| Definition | Point mutations in DNA gyrase subunit B (gyrB) can result in resistance to aminocoumarins. These mutations usually involve arginine residues in organisms. |
| Drug Class | aminocoumarin antibiotic |
| Resistance Mechanism | antibiotic target alteration |
| Classification | 8 ontology terms | Show + process or component of antibiotic biology or chemistry + mechanism of antibiotic resistance + antibiotic target alteration [Resistance Mechanism] + mutation conferring antibiotic resistance + determinant of antibiotic resistance + antibiotic resistant gene variant or mutant + antibiotic resistant DNA topoisomerase subunit + antibiotic molecule |
