The thesis committee for rebecca rose morrison certifies that this is the approved version of the following thesis: purification of feo proteins and analysis of residues important for feo the siderophore enterobactin binds ferric iron with high affinity, which enables it.
Siderophore structures have been characterized from the field, lab and field experiments show that siderophores are a component of this pool (haygood et al 1993, rue and bruland 1995, lewis et al 1995, wilhelm et al 1998, hudson 1998, hutchins et al. Review of literature studies on siderophore production by streptomyces sp ph d thesis, manisha s bendale, 2010, nmu, jalgaon1 11] introduction: nearly all living organisms require iron for metabolic activities and growth. This thesis describes the inflammatory properties of siderophores and how siderophore secretion by k pneumoniae impacts bacterial infection in vitro, respiratory epithelial cells treated with siderophores and the host protein lcn2 induced secretion of pro-inflammatory cytokines including il-8, il-6, and ccl20.
Activation of otherwise unreactive substrates is a common strategy in chemistry and in nature adenylate-forming enzymes use adenosine monophosphate to activate the hydroxyl of their carboxylic substrate, creating a better leaving group. Bacteria possess complex machinery for uptake of essential iron studying iron-uptake provides insight into requirements for bacterial growth, and for development of applications, including novel antibiotics and diagnostic tools the presented project investigates the binding of periplasmic binding proteins ceue, fepb and vctp with a range of iron(iii)-siderophore and siderophore-mimic compounds.

Iii sequence of t virens revealed the presence of three genes, tex10, tex20, and tex21 that encode siderophore-producing enzymes known as non-ribosomal peptide synthetases (nrpss), but their regulation and function are largely unknown. Once bound, the now soluble iron-siderophore complex is taken up by specific receptors on the surfaces of bacteria or plants, internalized and then following either reduction to the ferrous state.
