General description

Chemical structure: peptide

Application

Bacitracin zinc salt is a peptide antibiotic used to study dysruption of bacterial cell wall synthesis at the level of peptidoglycan biosynthesis and isoprenyl metabolism. It is used to study the biosynthesis of sterols and squalene.

Biochem/physiol Actions

Bacitracin is a protease inhibitor. Antimicrobial spectrum: Gram-positive bacteria.
Mode of Action: Inhibits bacterial cell wall synthesis by inhibiting dephosphorylation of lipid pyrophosphate.

Other Notes

Keep container tightly closed in a dry and well-ventilated place.
