A two-iron-two-sulphur non-haem iron protein, the ferredoxin from Spirulina maxima, has been studied by means of electron paramagnetic resonance (EPR) in the range where the spectrum loses resolution with increasing temperature. The spin... JP Gayda,JF Gibson,R Cammack,... - BBA - Protein...
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...

Iron (Fe) is an essential micronutrient for human growth and health. Organic iron is an excellent iron supplement due to its bioavailability. Both amino acids and peptides improve iron bioavailability and absorption and are therefore valuable components of iron supplements. This review focuses on pro...
Reduction of viologen dyes and a non-haem iron protein by NADH in particles from Azotobacter vinelandiiIn cell-free extracts of Micrococcus denitrificans, phosphorylation associated with the reduction of nitrate was observed with NADH2, succinate, malate, pyruvate or glutamate as hydrogen donors. ...

The canonical structural motif for co-ordination of non-haem ferrous iron in metal-dependent oxygenases is a facial triad of two histidine residues and one aspartate or glutamate residue. This so-called 2-His-1-carboxylate metallocentre is often accommodated in a double-stranded beta-helix fold ...
