背景说明 |
是一种抗菌和两亲性肽,对多种革兰氏阴性和革兰氏阳性细菌均表现出抗菌活性。 |
生物活性 |
Magainin 1 是从爪蟾皮肤中分离出来的一种抗菌两亲肽,对多种革兰氏阴性和革兰氏阳性细菌具有抗菌活性。[1-2] |
In Vitro |
Magainin 1 induces the leakage of calcein specifically out of negatively-charged vesicles. Magainin 1 induces the leakage of calcein specifically out of negatively-charged vesicles. The peptide binds to bovine brain phosphatidylserine sonicated vesicles according to the Langmuir isotherm with a binding constant of 3.8.10(5)M-1 and a binding-site number of 0.10 per lipid molecule. Magainin 1 interacts with acidic lipids through electrostatic interactions followed by hydrophobic interactions to form an amphiphilic helix,inducing the leakage.[1] |
