一般說明
肠菌素合成通过非核糖体的肽合成酶发生。前体分支酸转化为中间体异分支酸、2,3-二氢-2,3-二羟基苯甲酸酯和 2,3-二羟基苯甲酸（DHB）。最后一步涉及 DHB 和 L-丝氨酸酰胺键。共有六种酶（ent A −F）介导肠菌素的生物合成。
應用
肠菌素已用于：
- 用作色氨酸荧光猝灭实验中的阳性对照
- 用作高效液相色谱定量玉米联合固氮菌培养基的参考标准品
- 结晶储层（用于去除培养基中的铁污染）以及铁肠菌素结合研究
这种肠杆菌素制剂不与铁结合，而是与溶液中的 Fe3+ 和 Fe2+结合。
生化／生理作用
微生物对铁的动员和吸收是由被称为铁载体（siderophore）的低分子量络合剂介导的。 肠杆菌素是一种儿茶酚（一种苯二醇，C6H4(OH)2)型铁载体，由大肠杆菌和相关肠道细菌在缺铁培养基上生长时少量产生，是已知的最强大的铁离子络合剂之一。 肠杆菌素是一种非常有效的铁螯合剂，能够去除蛋白质、不溶性铁络合物和其它铁载体中的铁。 对肠杆菌素的化学、调节、合成、识别和运输的研究使其成为人们最了解的铁载体。
