Mupirocin inhibits bacterial protein synthesis by specific reversible binding to bacterial isoleucyl tRNA synthase. With excellent activity against gram-positive staphylococci and streptococci, it is primarily used for treatment of primary and secondary skin disorders, nasal infections, and wound healing.
