Template:Short description

Script error: No such module "Infobox".Template:Template other Lactoferricin is an amphipathic, cationic peptide with anti-microbial[1] and anti-cancer[2] properties. It can be generated by the pepsin-mediated digestion of lactoferrin.

Lactoferricin is the most studied AMP derived from milk protein. The complete sequence of lactoferricin corresponds to lactoferrin fragment 17-41 (FKCRRWQWRM KKLGAPSITCVRRAF; LFB0084 Template:Webarchive) and sequences from within this fragment are also antimicrobial. The MilkAMP database contains a total of 111 peptides (natural, synthetic and modified) comprising or derived from the complete lactoferricin.[1] In humans, lactoferricin corresponds to lactoferrin fragment 1-47 but consists of two subunits, namely fragments 1-11 and 12-47 (LFH0009 Template:Webarchive), connected by a disulfide bridge.[3]

Human Lactoferricin and Bovine Lactoferricin are two greatly studied forms of Lactoferricin. These two forms have great sequence differences. Bovine Lactoferricin contains 25 residues, while Human Lactoferricin contains 49 residues.[4] Also, when placed in solution Bovine Lactoferricin forms a β-pleated sheet, while Human Lactoferricin forms a coiled structure.[5]
