Mupirocin calcium hydrate(CAT: R045881) is a naturally derived antibiotic produced by Pseudomonas fluorescens, supplied in its stable calcium hydrate form. It selectively inhibits bacterial isoleucyl-tRNA synthetase, thereby blocking protein synthesis and exerting potent bacteriostatic or bactericidal effects depending on concentration. Mupirocin shows strong activity against Gram-positive organisms, particularly Staphylococcus aureus (including MRSA), and Streptococcus species. It is widely used in microbiology and pharmacology research for studying antibacterial mechanisms, resistance development, and topical antimicrobial therapy. Mupirocin calcium hydrate serves as a reliable tool for investigating protein synthesis inhibition, bacterial physiology, and antibiotic development.
