The Antimicrobial peptide databases may be divided into two categories on the basis of the source of peptides it contains, as specific databases and general databases. These databases have various tools for antimicrobial peptides analysis and prediction. For example, the APD has a widely used calculation interface.
Lantibiotics are produced by Gram-positive bacteria and show strong antimicrobial action toward a wide range of other Gram-positive bacteria. [14] As such, they have become attractive candidates for use in food preservation (by inhibiting pathogens that cause food spoilage) and the pharmaceutical industry (to prevent or fight infections in ...
Nisin is a polycyclic antibacterial peptide produced by the bacterium Lactococcus lactis that is used as a food preservative.It has 34 amino acid residues, including the uncommon amino acids lanthionine (Lan), methyllanthionine (MeLan), didehydroalanine (Dha), and didehydroaminobutyric acid (Dhb).

The peptides will therefore exchange place with those ions, thus affecting the stability of the membrane. [5] The peptides have a greater size compared with the ions which cause changes in the membrane structure. [5] Due to changes in the electric potential, peptides will pass across the membrane and thus aggregate into dimers. [9]
Class IIa bacteriocins have a large potential for use in food preservation as well medical applications due to their strong anti-Listeria activity and broad range of activity. One example of Class IIa bacteriocin is pediocin PA-1. [13] The class IIb bacteriocins (two-peptide bacteriocins) require two different peptides for activity.
Bacillus amyloliquefaciens is a species of bacterium in the genus Bacillus that is the source of the BamHI restriction enzyme. It also synthesizes a natural antibiotic protein barnase, a widely studied ribonuclease that forms a famously tight complex with its intracellular inhibitor barstar, and plantazolicin, an antibiotic with selective activity against Bacillus anthracis.
Bacitracin is a polypeptide antibiotic derived from a bacterium, Bacillus subtilis, and acts against bacteria through the inhibition of cell wall synthesis. [6] It does this by inhibiting the removal of phosphate from lipid compounds, thus deactivating its function to transport peptidoglycan; the main component of bacterial cell membranes, to the microbial cell wall.
