    • The present invention relates to an isolated cyclic peptide, theta defensin, having antimicrobial activity, and to theta defensin analogs. A theta defensin can have the amino acid sequence Xaa1-Xaa2-Xaa3-Xaa4-Xaa5-Xaa1-Xaa6-Xaa4-Xaa4-Xaa1-Xaa1-Xaa6-Xaa4-Xaa5-Xaa1-Xaa3-Xaa7-Xaa5, wherein Xaa1 to Xaa8 are defined; wherein Xaa1 can be linked through a peptide bond to Xaa8; and wherein crosslinks can be formed between Xaa3 and Xaa3, between Xaa5 and Xaa5, and between Xaa7 and Xaa7. For example, the invention provides a theta defensin having the amino acid sequence Gly-Phe-Cy-Arg-Cys-Leu-Cys-Arg-Arg-Gly-Val-Cys-Arg-Cys-Ile-Cys-Thr-Arg (SEQ ID NO:1), wherein the Gly at position 1 (Gly-1) is linked through a peptide bond to Arg-18, and wherein disulfide bonds are present between Cys-3 and Cys-16, between Cys-5 and Cys-14, and between Cys-7 and Cys-12. The invention also relates to antibodies that specifically bind a theta defensin and to isolated nucleic acid molecules encoding a theta defensin. In addition, the invention relates to methods of using theta defensin or a theta defensin analog to reduce or inhibit microbial growth or survival in an environment capable of sustaining microbial growth or survival by contacting the environment with the theta defensin.
    • 本发明涉及具有抗微生物活性的分离的环肽,θ防御素,以及θ防御素类似物。 θ防御素可以具有氨基酸序列Xaa1-Xaa2-Xaa3-Xaa4-Xaa5-Xaa1-Xaa6-Xaa4-Xaa4-Xaa1-Xaa1-Xaa6-Xaa4-Xaa5-Xaa1-Xaa3-Xaa7-Xaa5,其中Xaa1至Xaa8是 定义 其中Xaa1可通过肽键与Xaa8连接; 并且其中可以在Xaa3和Xaa3之间,Xaa5和Xaa5之间以及Xaa7和Xaa7之间形成交联。 例如,本发明提供具有氨基酸序列Gly-Phe-Cy-Arg-Cys-Leu-Cys-Arg-Arg-Gly-Val-Cys-Arg-Cys-Ile-Cys-Thr-Arg的θ防御素 SEQ ID NO:1),其中位置1处的Gly(Gly-1)通过肽键与Arg-18连接,并且其中二硫键存在于Cys-3和Cys-16之间,Cys-5和Cys之间 -14,以及Cys-7和Cys-12之间。 本发明还涉及特异性结合θ防御素和编码θ防御素的分离的核酸分子的抗体。 此外,本发明涉及使用θ防御素或θ防御素类似物以通过使环境与θ防御素接触来在能够维持微生物生长或存活的环境中减少或抑制微生物生长或存活的方法。
