MASS SPECTROMETRY-DERIVED SYSTEMS BIOLOGY TECHNOLOGIES DELINEATE THE SYSTEM'S BIOCHEMICAL APPLICATIONS OF SIDEROPHORES

摘要

Siderophores are chemically diverse secondary metabolites that primarily assist the host organisms to chelate iron. Siderophores are biosynthesized by many biological organisms, including bacteria, fungi, and plants and they are responsible for a variety of biological functions beyond capture iron. Thus, they could provide a novel understanding of host-pathogen interactions, plant physiology, disease pathogenesis, and drug development. However, knowledge gaps in analytical technologies, chemistry, and biology have severely impeded the applications of siderophores, and a new strategy is urgently needed to bridge these gaps. Mass spectrometry (MS) and associated technologies render unparalleled advantages in this niche in terms of high throughput, resolution, and sensitivity. Herein, this critical review briefly summarizes progress in the study of siderophores and specifically identifies MS-based novel strategies that attempt to mimic the complexity of siderophore systems in order to increase the applicability of these compounds in the scientific community.
