process or component of antibiotic biology or chemistry antibiotic target antibiotic_resistance ARO:3000708 Antibiotic targets are components of the bacterial or fungal cell. Bacterial targets are usually significantly different from their eukaryotic counterparts to allow for selective antibacterial activity. Exceptions include antibiotics that are converted to an active form inside the bacterium. Resistance mechanisms may modify these targets to protect bacteria or fungi from the effects of antibiotics.
