詳細

General description

Cecropin A belongs to cecropin class[1] and comprises 37 amino acid residues in L configuration.[2] Structurally, this peptide has a C-terminal hydrophobic α-helical structure and the amphipathic N-terminal end.[1] Cecropin A is linear and cationic in nature.[3]

Application

Cecropin A has been used as an antimicrobial peptide (AMP):

• to test its cytotoxic effect on breast adenocarcinoma (MDA-MB-231) and human mesothelioma (M14K) cell lines[1]
• in ultrasensitive radial diffusion assay against E coli to test Galleria mellonella protein 24 and apolipophorin III effects[4]
• to test its minimal inhibitory concentrations (MICs) in sensitivity assay for Photorhabdus variants[4]

Biochem/physiol Actions

抗菌性ペプチド

もともとガHyalophora cecropiaから、後にブタ腸から単離された、抗菌ペプチドです。

Cecropin A interacts with cell membranes and makes it permeable for electrolytes. Cecropin A thus, favors cytolysis and finally cell death in the hepatocellular carcinoma and lymphoma.[1] The synthetic cecropin A in transgenic rice confers protection against bacterial as well as fungal pathogens.[3]
