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.
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).

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.
Nutritional immunology is a field of immunology that focuses on studying the influence of nutrition on the immune system and its protective functions. Indeed, every organism will under nutrient-poor conditions "fight" for the precious micronutrients and conceal them from invading pathogens.
Bradykinin (BK) (from Greek brady-'slow' + -kinin, kīn(eîn) 'to move') is a peptide that promotes inflammation.It causes arterioles to dilate (enlarge) via the release of prostacyclin, nitric oxide, and endothelium-derived hyperpolarizing factor and makes veins constrict, via prostaglandin F2, thereby leading to leakage into capillary beds, due to the increased pressure in the capillaries.
This peptide consists of a core peptide segment which is typically preceded (and occasionally followed) by a leader peptide segment and is typically ~20-110 residues long. The leader peptide is usually important for enabling enzymatic processing of the precursor peptide via aiding in recognition of the core peptide by biosynthetic enzymes and ...
