Streptothricin F is effective against highly drug-resistant gram-negative bacteria, including carbapenem-resistant E. coli. [3] NTC can be inactivated by nourseothricin N-acetyl transferase (NAT) from Streptomyces noursei, an enzyme that acetylates the beta-amino group of the beta-lysine residue of NTC. [4] NAT can thus act as an antibiotic ...
