일반 설명

Chemical structure: peptide

애플리케이션

PGLa is a cationic antimicrobial peptide (AMP) originally isolated from frog. It has been shown to have antibacterial,1 antifungal,2 and antiviral,3 activities. It is used to study novel peptide fragments that originate from PGLa[1] and multinucleated gastric mucosal cells of Xenopus laevis[2].

생화학적/생리학적 작용

The precursors of PGLa are caerulein and xenopsin[1]. The mechanism of action of PGLa against Gram-negative bacteria is disruption of the cellular lipid bilayer.4 It is used to induce transmembrane pore formation in lipid bilayers and bacterial cell membranes. It is used in combination with magainin 2 for a synergistic effect.
