| Synonym(s) | Nakaseomyces glabratus |
| Definition | Glucan synthase FKS2 is involved in the production of the fungal cell wall by the synthesis of the core component beta-1,3-glucan in Candida spp. Mutations in FKS2 have been shown to confer resistance to echinocandin antibiotic micafungin. |
| AMR Gene Family | echinocandin-resistant beta-1,3-D-glucan synthase |
| Drug Class | echinocandin antibiotic |
| Resistance Mechanism | antibiotic target alteration |
| Classification | 11 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 target + antibiotic molecule + antibiotic resistance gene variant or mutant + antifungal resistant beta-1,3-glucan synthase + echinocandin antibiotic [Drug Class] + cell wall synthesis enzyme targeted by antibiotic |
