today. Lipopeptide is a research chemical and not for human use. So far, studies show it can increase cell production in collagen to give smoother skin and reduce wrinkles. Here we delve into more about lipopeptides.
WHAT ARE LIPOPEPTIDES?
Lipopeptides are used as antibiotics and antifungal and antitumor agents.
Lipopeptide Antibiotics Example
Some of the lipopeptides examples that are used as antibiotics are:
Lincomycin
Aureomycin
Teicoplanin
Lipopeptide Antibiotics Mechanism
The structure of lincomycin is a cyclic hexapeptide with a side chain of 2 lysines (shown in yellow). Lincomycin prevents protein synthesis by binding to ribosomes. This binding prevents protein synthesis and the formation of peptidyl transferases. If you are in the research and science community and want to buy Lipopeptide peptide – click here now!
How do lipopeptide antibiotics work?
The structure of aureomycin is similar to lincomycin. Aureomycin does not prevent the formation of peptidyl transferases but it blocks the elongation of newly made proteins. This leads to the eventual inhibition of protein synthesis. The aureomycin molecule is attached to a carrier molecule called teicoplanin and these complexes bind to ribosomes.
HOW DO LIPOPEPTIDES WORK?
The structure of teicoplanin is shown below. Teicoplanin binds to two different sites in the ribosome. At each site, the teicoplanin binds to both rRNA (in gray) and ribosomal protein (in yellow).
Teicoplanin inhibits protein synthesis by preventing the synthesis of both new peptide bonds and the synthesis of ribosomes. This leads to cell death. Teicoplanin is the last antifungal agent used in human medicine.
HOW ARE LIPOPEPTIDES PRODUCED?
The production of lipopeptides is dependent on both the microorganism and the environment in which it is growing. Many of the lipopeptides are produced by soil bacteria. It makes them at low temperatures and in low nutrient conditions. Some lipopeptides are produced by fungi. The production of the teicoplanin complex is dependent on temperature and the pH of the growth medium.
