    Regulation of Siderophore Biosynthesis from Marine Vibrio anguillarum

    • 摘要: 以一株鳗弧菌pJM1质粒缺陷为研究对象,考察了儿茶酚类铁载体Anguibactin的合成代谢调控。研究发现:在由染色体和质粒共同编码介导的铁载体Anguibactin的合成途径中,其分界点位于2,3-二羟基苯甲酸合成,2,3-二羟基苯甲酸合成之前代谢途径受染色体编码调节,后由质粒编码介导;编码2,3-二羟基苯甲酸的染色体相关基因的表达受环境铁离子浓度的诱导调节。

       

      Abstract: Regulation of siderophore anguibactin biosynthesis was studied by using a mutant from marine Vibrio anguillarum which harbors a pJM1 plasmid. It was concluded that the siderophore biosynthesis is demarcated by 2,3 DHBA biosynthesis, and all steps before 2,3 DHBA synthesis were mediated by chromosome while the other steps were mediated by plasmid. Expression of genes on chromosome for biosynthesis of 2,3 DHBA was induced by environmental ferric ion.
