We have applied computational procedures that utilize nmr data to model the solution conformation of ferrichrome, a rigid microbial iron transport cyclohexapeptide of known x-ray crystallographic structure [D. van der Helm et al. (1980) J. Am. Chem. Soc. 102, 4224-4231].

The siderophore synthetic system in Shewanella species is able to synthesize dozens of macrocyclic siderophores in vitro with synthetic precursors. In vivo, however, although three siderophores are produced naturally in Shewanella algae B516, which carries a lysine decarboxylase (AvbA) specific

Desferriferricrocin is a cyclic hexa-peptide siderophore with three hydroxamates as primary coordination groups. It forms metal complexes with Fe(III), Cr(III), Al(III), Ga(III), Cu(II), and Zn(II). These complexes were prepared and characterized using UV-vis, circular dichroism spectroscopy (CD), nuclear magnetic resonance

The biodistribution of 67Ga-labelled complexes of some mono- and di-N-hydroxyamino acid derivatives and of two siderophores (trihydroxamates) were evaluated in Rhabdomyosarcoma-bearing rats. It was found that the mono- and dihydroxamates could not enhance the tumour-localizing properties of 67Ga-citrate, while the

Colorectal cancers develop through several pathways, including the adenoma-carcinoma sequence and colitis-associated carcinogenesis. An altered intestinal microflora has been reported to be associated with the development and progression of colorectal cancer via these pathways. We identified Lactobacillus casei-derived ferrichrome as
