“As shown here, Mn(II) inhibits ferroxidase activity, suggesting that ferroxidation may be prevented in vivo as D. radiodurans accumulates a high ratio of Mn: Fe.”
“We suggest that elevated Mn(II) displaces iron from cellular‐binding sites and the resulting rise in free iron levels leads to repression of the Fur regulon.”
“The binding of the Mn(II) Fur complex to a DNA fragment " iron box " has a slight broadening effect on the Mn(II) signal and hence it altered the symmetry of the Mn(II) environment.”
