PGLa is an antimicrobial peptide from the magainin family found within the granular gland secretions of the skin of the Xenopus laevis frog. It displays a broad spectrum against Gram-positive and Gram-negative bacteria. PGLa peptide also displays antifungal activity against C. albicans. PGLa peptide corresponds to aa39-59 of PYLa/PGLa A precursor after cleavage into PYLa, PGLa and PGLa-H.Frog: H-Gly-Met-Ala-Ser-Lys-Ala-Gly-Ala-Ile-Ala-Gly-Lys-Ile-Ala-Lys-Val-Ala-Leu-Lys-Ala-Leu-NH2 or H-GMASKAGAIAGKIAKVALKAL-NH2
