Engineering siderophores.
Siderophores have important functions for bacteria in iron acquisition and as virulence factors. In this chapter we will discuss the engineering of cyclic hydroxamate siderophores by various biochemical approaches based on the example of Shewanella algae. The marine gamma-proteobacterium S. algae produces three different cyclic hydroxamate siderophores as metabolites via a single biosynthetic gene cluster and one of them is an important key player in interspecies competition blocking swarming of Vibrio alginolyticus. AvbD is the key metabolic enzyme assembling the precursors into three different core structures and hence an interesting target for metabolic and biochemical engineering. Synthetic natural and unnatural precursors can be converted in vitro with purified AvbD to generate siderophores with various ring sizes ranging from analytical to milligram scale. These engineered siderophores can be applied, for example, as swarming inhibitors against V. alginolyticus. Here, we describe the synthesis of the natural and unnatural siderophore precursors HS[X]A and provide our detailed protocols for protein expression of AvbD, conversion of HS[X]A with the enzyme to produce ring-size engineered siderophores and secondly for a biosynthetic feeding strategy that allows to extract engineered siderophores in the milligram scale.

Simultaneous biosynthesis of putrebactin, avaroferrin and bisucaberin by Shewanella putrefaciens and characterisation of complexes with iron(III), molybdenum(VI) or chromium(V).
Cultures of Shewanella putrefaciens grown in medium containing 10mM 1,4-diamino-2-butanone (DBO) as an inhibitor of ornithine decarboxylase and 10mM 1,5-diaminopentane (cadaverine) showed the simultaneous biosynthesis of the macrocyclic dihydroxamic acids: putrebactin (pbH Topics: Bacterial Proteins; Cadaverine; Chromium; Coordination Complexes; Diamines; Electron Spin Resonance Spectroscopy; Gene Expression; Hydroxamic Acids; Iron; Molybdenum; Ornithine Decarboxylase; Ornithine Decarboxylase Inhibitors; Peptides, Cyclic; Putrescine; Shewanella putrefaciens; Succinates | 2016 |
