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.

The first structures of these antimicrobial agents were produced by pioneering work by Gross and Morell in the late 1960s and early 1970s, thus marking the formal introduction of lantibiotics. Since then, lantibiotics such as nisin have been used auspiciously for food preservation and have yet to encounter significant bacterial resistance .
It includes the alpha enterocins and lactococcin G peptides. These peptides have some antimicrobial properties; they inhibit the growth of Enterococcus spp. and a few other Gram-positive bacteria. These peptides act as pore-forming toxins that create cell membrane channels through a barrel-stave mechanism and thus produce an ionic imbalance in ...
The name 'defensin' was coined in the mid-1980s, though the proteins have been called 'Cationic Antimicrobial Proteins,' 'Neutrophil peptides,' 'Gamma thionins' amongst others. [6] Proteins called 'defensins' are not all evolutionarily related to one another. [7] Instead fall into two broad superfamilies, each of which contains multiple families.
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 beta defensins are antimicrobial peptides implicated in the resistance of epithelial surfaces to microbial colonization. Defensins are 2 to 6 kDa, cationic, microbicidal peptides active against many Gram-negative and Gram-positive bacteria, fungi, and enveloped viruses, [ 1 ] containing three pairs of intramolecular disulfide bonds.
