The ferritin iron entry and exit problem

Theil, E. C., Takagi, H., Small, G. W., He, L., Tipton, A. R., & Danger, D. (2000, January 1). Inorganica Chimica Acta.

By: E. Theil*, H. Takagi  n, G. Small n, L. He n, A. Tipton & D. Danger n

author keywords: ferritin; iron biominerals; ferroxidation; iron/dioxygen catalysis
topics (OpenAlex): Iron Metabolism and Disorders; Trace Elements in Health; Hemoglobinopathies and Related Disorders
TL;DR: The entry and exit of Fe(II) ions in ferritin are endpoints in the process which concentrates iron as a solid (hydrated ferric oxide) to be used by living cells, suggesting a regulation-sensitive biological signal for iron exit. (via Semantic Scholar)

MeSH headings : Animals; Anura; Biopolymers; Electron Spin Resonance Spectroscopy; Ferric Compounds / chemistry; Ferritins / chemistry; Minerals / chemistry; Oxidation-Reduction; Recombinant Proteins / chemistry; Spectroscopy, Mossbauer
topics (OpenAlex): Iron Metabolism and Disorders; Trace Elements in Health; Plant Micronutrient Interactions and Effects
TL;DR: The subsequent decay of these multiple Fe3-oxy species to the superparamagnetic mineral suggests that Fe3+ species in different environments may be translocated as intact units from the protein shell into the ferritin cavity where the conversion to a solid mineral occurs.

1997 article

The influence of conserved tyrosine 30 and tissue-dependent differences in sequence on ferritin function: use of blue and purple Fe(III) species as reporters of ferroxidation

Fetter, J., Cohen, J., Danger, D., Sanders-Loehr, J., & Theil, E. C. (1997, October 1). JBIC Journal of Biological Inorganic Chemistry.

By: J. Fetter n, J. Cohen *, D. Danger n, J. Sanders-Loehr* & E. Theil n

topics (OpenAlex): Iron Metabolism and Disorders; Hemoglobinopathies and Related Disorders; Porphyrin Metabolism and Disorders
TL;DR: The impact of Y30F on rates of formation of Fe(III)-protein complexes in ferritin, combined with Mössbauer spectroscopic studies, indicate that at least one of the pathways for Fe oxidation/transfer in Ferritin is through the center of the four-helix bundle and is influenced by structural features dependent on tyrosine 30.
