说明

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[1]
as a control antibiotic[2]
for the calibration in size exclusion chromatography[3]

生化/生理作用

Bacitracin has been shown to decrease vancomycin-resistant Enterococcus faecium population in intestine.[4]

Peptide antibiotic.
Antimicrobial spectrum: Gram-positive bacteria.
Mode of Action: Inhibits bacterial cell wall synthesis by inhibiting dephosphorylation of lipid pyrophosphate.

其他说明

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