What is Lactoferricin B?
At its core, lactoferricin B (often abbreviated as LfcinB) is a potent antibacterial peptide. It is essentially a 25-residue antimicrobial peptide that is generated upon gastric pepsin cleavage of lactoferrin, an 80 kDa iron-binding glycoprotein found in milk and colostrum. Because it is derived from bovine lactoferrin, it is frequently classified as a highly basic bioactive peptide.
From a structural perspective, LfcinB is defined as a peptide derived from bovine lactoferrin that exhibits a unique amphipathic, cationic peptide architecture. This specific molecular arrangement, often described as an anti-parallel β-sheet structure, is crucial to how it interacts with various biological surfaces.
