CD and MCD spectroscopic studies of the two Dps miniferritin proteins from Bacillus anthracis: role of O2 and H2O2 substrates in reactivity of the diiron catalytic centers.
Schwartz JK, Liu XS, Tosha T, Diebold A, Theil EC, Solomon EI. Schwartz JK, et al. Biochemistry. 2010 Dec 14;49(49):10516-25. doi: 10.1021/bi101346c. Epub 2010 Nov 12. Biochemistry. 2010. PMID: 21028901 Free PMC article.
The data show a single 5- or 6-coordinate Fe(II) in the absence of oxidant; Fe(II) binding to Dps2 is 30 more stable than Dps1; and the lower limit of K(D) for binding a second Fe(II), in the absence of oxidant, is 2-3 orders of magnitude weaker than for the binding of the …

The ferritin Fe2 site at the diiron catalytic center controls the reaction with O2 in the rapid mineralization pathway.
Tosha T, Hasan MR, Theil EC. Tosha T, et al. Proc Natl Acad Sci U S A. 2008 Nov 25;105(47):18182-7. doi: 10.1073/pnas.0805083105. Epub 2008 Nov 14. Proc Natl Acad Sci U S A. 2008. PMID: 19011101 Free PMC article.
Ferritin with Asp(140), Ser(140), or Ala(140) formed diferric peroxo intermediates with variable kinetic stabilities and rates: t(1/2) varied 1- to 10-fold; k(cat) varied approximately 2- to 3-fold. Thus, relatively small differences in diiron protein catalytic sites deter …

Together with the results on L358P in which the amide proton at position 358 was removed (Yoshioka, S., Takahashi, S., Ishimori, K., Morishima, I. J. Inorg. Biochem. 2000, 81, 141-151), we propose that the side chain hydrogen bond and the electrostatic interaction of the a …
