General description

Chemical structure: peptide

Application

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

Biochem/physiol Actions

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

Packaging

5G, 25 G

Heptaprenyl diphosphate (C35 -PP) is an isoprenoid intermediate in the synthesis of both menaquinone and the sesquarterpenoids. We demonstrate that inactivation of ytpB, encoding a C35 -PP utilizing enzyme required for sesquarterpenoid synthesis, leads to an increased sensitivity to bacitracin

Inhibition of Cell Wall Biosynthesis by Antibiotics

The specificity of β-lactam antibacterials is due to their ability to inhibit transpeptidase enzymes and prevent the assembly of the peptidoglycan layer in both Gram-positive and Gram-negative bacteria.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
