TL;DR: The functional forms of biominerals, R.P.Williams crystallochemical strategies in biomineralization, S.Mann and R.C.Perry ferritin - function and structural design of an iron storage protein, P.Webb and C.Birchall.

TL;DR: Several low molecular mass proteins tightly bound to bacterial magnetite were obtained from Magnetospirillum magneticumstrain AMB-1 and showed common features in their amino acid sequences, which may be directly involved in biological magnetite crystal formation in magnetic bacteria.

TL;DR: Ferritin cores from human spleen, limpet (Patella vulgata) haemolymph and bacterial cells have been investigated using 57Fe Mössbauer spectroscopy and show typical superparamagnetic behaviour, while those from the bacterial ferritin show behaviour corresponding to a transition from a magnetically ordered to a paramagnetic state.

TL;DR: The data support that Chit acts as steric stabilizer and inhibits the macroscopic aggregation of the subcolloidal FeOOH particles, thus the iron(III)-Chit interactions offer a simple and economic way to fabricate nanometric size FeOOh spheres, morphologically similar to the core of iron( III)-storage protein, ferritin.

TL;DR: In this paper, the formation constants for the iron(III) complexes of the orally effective iron chelator pyridoxal isonicotinoyl hydrazone (PIH) and three analogues were determined by a combination of spectrophotometry and potentiometry.
