Electrospray mass spectrometry and automated Edman sequencing provides the structures of two new caerin 1 antimicrobial peptides from the skin glands of the Australian tree frog Litoria chloris. These are: caerin 1.8 Gly Leu Phe Lys Val Leu Gly Ser Val Ala Lys His Leu Leu Pro His Val Val Pro Val Ile Ala Glu Lys Leu (NH2), and caerin 1.9, Gly Leu Phe Gly Val Leu Gly Ser Ile Ala Lys His Val Leu Pro His Val Val Pro Val Ile Ala Glu Lys Leu (NH2).
电喷雾质谱法和自动埃德曼测序法确定了两种来自澳大利亚绿树蛙(Litoria chloris)皮肤腺体的新型caerin 1抗菌肽的结构。它们分别是:caerin 1.8,甘氨酸-亮氨酸-苯丙氨酸-赖氨酸-缬氨酸-亮氨酸-甘氨酸-丝氨酸-缬氨酸-丙氨酸-赖氨酸-组氨酸-亮氨酸-亮氨酸-脯氨酸-组氨酸-缬氨酸-缬氨酸-脯氨酸-缬氨酸-异亮氨酸-丙氨酸-谷氨酸-赖氨酸-亮氨酸(NH2),以及caerin 1.9,甘氨酸-亮氨酸-苯丙氨酸-甘氨酸-缬氨酸-亮氨酸-甘氨酸-丝氨酸-异亮氨酸-丙氨酸-赖氨酸-组氨酸-缬氨酸-亮氨酸-脯氨酸-组氨酸-缬氨酸-缬氨酸-脯氨酸-缬氨酸-异亮氨酸-丙氨酸-谷氨酸-赖氨酸-亮氨酸(NH2)。
