一般描述

Chemical structure: peptide

应用

Bacitracin is used to study disruption of bacterial cell wall synthesis at the level of peptidoglycan biosynthesis and isoprenyl metabolism. It is also used to study the biosynthesis of sterols and squalene.
Bacitracin has been used:
  • as a protease inhibitor
  • as a control antibiotic
  • for the calibration in size exclusion chromatography

生化/生理作用

Peptide antibiotic.
Antimicrobial spectrum: Gram-positive bacteria.
Mode of Action: Inhibits bacterial cell wall synthesis by inhibiting dephosphorylation of lipid pyrophosphate.
Bacitracin has been shown to decrease vancomycin-resistant Enterococcus faecium population in intestine.

包装

5G, 25 G
