摘　　要：以一株鳗弧菌 p JM1质粒缺陷株为研究对象 ,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 ,之后由质粒编码介导 ;编码 2 ,3Regulation 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.
