Mupirocin (pseudomonic acid A, or Bactroban or Centany) is an antibiotic originally isolated from Pseudomonas fluorescens. It is used topically, and is primarily effective against Gram-positive bacteria. Mupirocin is bacteriostatic at low concentrations and bactericidal at high concentrations. Mupirocin has a unique mechanism of action, which is selective binding to bacterial isoleucyl-tRNA synthetase, which halts the incorporation of isoleucine into bacterial proteins. Because this mechanism of action is not shared with any other antibiotic, mupirocin has few problems of antibiotic cross-resistance.

Mupirocin apparently exerts its antimicrobial activity by reversibly inhibiting isoleucyl-transfer RNA, thereby inhibiting bacterial protein and RNA synthesis[1][2].
