일반 설명

Chemical structure: peptide

애플리케이션

Bactenecin′s activity has been studied as a cyclic molecule as well as in a linear form. It was used to study the functional role of Trk1p in the mechanism of other antifungal peptides. It has been used to study chemokine and cytokine production, alteration of gene expression in host cells, and inhibition of proinflammatory responses of host cells to bacterial components.

생화학적/생리학적 작용

Bactenecin is a 12-amino acid cationic antimicrobial peptide from bovine neutrophils. It strongly binds to LPS and perturbs the structure, fluidity and permeability of the inner membrane. This results in the leakage of cytosol and subsequent death of the bacteria.

기타 정보

Peptide antibiotic, originally isolated from bovine neutrophil granules

Cytoplasmic granules of neutrophils store a variety of cationic polypeptides, which exert in vitro a potent antibacterial action and are potentially involved in host defense mechanisms. From an acid extract of bovine neutrophil granules we have purified over 2,000-fold a

Salivary histatin 5 (Hst 5) kills the fungal pathogen Candida albicans via a multistep process which includes binding to Ssa1/2 proteins on the cell surface and requires the TRK1 potassium transporter. Hst 5-induced membrane permeability to propidium iodide (PI) was

Intracellular pathogens selected for increased susceptibility to polycations are commonly attenuated, yet the effect of decreased susceptibility to polycations on pathogenicity has not been researched. The polymyxin-resistant mutant Brucella abortus AJ100 was characterized by comparing its susceptibility to the polycationic

Recent studies have demonstrated that in addition to their antimicrobial activity, cationic host defense peptides, like the human cathelicidin LL-37, perform many activities relating to innate immunity, including the induction or modulation of chemokine and cytokine production, alteration of gene
