The majority of Fur-regulated gene products are involved in iron uptake. Genes for transport and biosynthesis of enterobactin have been studied in E. coli K-12 (Earhart, 1996). It is assumed that this system is found in nearly every E. coli strain. Also the ferrichrome transport system seems to have a very broad distribution. The ferric citrate transport system (fee), however, is only present in some E. coli strains and may be part of a pathogenicity island. The aerobactin and yersiniabactin biosynthesis and transport systems are not found in all E. coli strains and are integrated into pathogenicity islands (Schubert et al., 1999). The ability to utilize haem seems also to be a specific pathogenicity-related adaptation. Haem transport systems are used in the animal or human host, where transferrin and lactoferrin create an iron-poor environment for bacteria. [Pg.112]

Hydrol5dic polymerization in the ferric citrate system can be prevented if sufficient excess citrate is present in solution 66). Approximately 20 millimolar excess citrate is sufficient to supress pol3mier-ization of 1 millimolar iron, as indicated by dialysis and spectrophotomet-ric measurements. From pH titration in high citrate solutions, it was concluded 66) that a dicitrate complex of iron is formed at high pH. Presumably formation of the dicitrate chelate is competitive with hydrolytic polymerization. The fraction of polymer formed in ferric citrate solutions was found to decrease smoothly as the citrate content was increased up to 20 millimolar. The nuclear relaxation rate of the water protons in ferric citrate solutions increases with the citrate concentration. [Pg.133]
