Both non-haem iron (iron salt) and haem iron (cytochrome c) are components of the Caenorhabditis elegans Maintenance Medium (CeMM). However, the quantitative requirements of non-haem iron and its relationship with haem iron were unknown. A basal medium was prepared with both non-haem iron and...
In contrast, non-haem iron intake was related inversely with lung cancer risk; however, this association attenuated after adjustment for smoking history. Additional adjustment for serum cotinine did not considerably alter the associations detected in the nested case–control subset.Greater haem iron ...

EPR studies of bacterioferritin (BFR), an iron-storage protein of Escherichia coli [1993, Biochem. J. 292, 47-56], have revealed the presence of non-haem iron (III) (NHI) sites within the protein coat which may be involved in iron uptake and release. When nitric oxide was used as an...
We propose that by sequestering haem and its bound iron, NCR247 creates a physiological state of haem deprivation. This in turn induces an iron-starvation response in rhizobia that results in iron import, which itself is required for nitrogenase activity. Using the same methods as for l-NCR247...
Mechanistic investigations showed that the N–F bond activation is the rate-determining step, and the strong preference for fluorination in the presence of excess NaN3 can be attributed to the spatial proximity of the carbon-centred radical to the iron-bound fluoride. This is a preview of ...
