Competitive binding of Fe3+, Cr3+, and Ni2+ to transferrin (Tf) was investigated at various physiological iron to Tf concentration ratios. Loading percentages for these metal ions are based on a two Mn+ to one Tf (i.e., 100% loading) stoichiometry and were determined using a particle beam/hollow cathode–optical emission spectroscopy (PB/HC-OES) method. Serum iron concentrations typically found in normal, iron-deficient, iron-deficient from chronic disease, iron-deficient from inflammation, and…

Significance of conformation changes during the binding and release of chromium(III) from human serum transferrin.
The Combined Effects of Iron Excess in the Diet and Chromium(III) Supplementation on the Iron and Chromium Status in Female Rats
TLDR
Evaluating the combined effects of supplementary of chromium(III) propionate complex (Cr3) with iron excess on the Cr and Fe status in healthy female rats proved a relationship between Fe( III) and Cr(III), however, the direction of change varied and depended on relative amounts of these elements in the diet.
Metal retention in human transferrin: consequences of solvent composition in analytical sample preparation methods.
TLDR
UV-VIS absorbance is employed here to monitor the iron content in human holo-transferrin (Tf) under various solvent conditions, changing polarity, pH, ionic strength, and the ionic and hydrophobic environment of the protein.

Non‐ideal metal binding model for Cr(III) sorption using Spirulina platensis biomass: Experimental and theoretical approach
Removal of Cr(III) from aqueous solution using Spirulina biomass was studied in a batch experiment. Spirulina biomass was characterised before and after Cr(III) sorption using FTIR, SEM and…

TLDR
The formation of the Tf-Tb3+ complex has been investigated by the employment of several biophysical techniques, such as fluorescence resonance energy transfer, “native” mass spectrometry (MS), and near-UV circular dichroism (CD).

Ti(IV) binds to human serum transferrin more tightly than does Fe(III).
TLDR
The binding of titanium(IV) to human serum transferrin in 50 mM Tris with 20 mM bicarbonate and 10 mM citrate at pH 7.4 was studied by UV/vis kinetics and by isothermal titration calorimetry, revealing the strength of metal binding to transferrin correlates with the Lewis acidity of the metal.
Instrumental comparison of the determination of Cr³+ uptake by human transferrin.
TLDR
Evidence that the PB/HC-OES method is a valid technique for investigating metal-protein complexes is provided providing evidence that the Cr³+ loading is elevated over a 24 h incubation time, but under physiological conditions the loading is inhibited.
Reconsideration of serum Ti(IV) transport: albumin and transferrin trafficking of Ti(IV) and its complexes.
TLDR
It is speculated that the formation of an M2HsTf complex of high affinity may predict a lobe-closed conformation that leads to a favorable interaction with TfR1, and has implications for the metabolism of Ti(IV) in human serum.

TLDR
Methods for the study of the differences between the two metal binding sites (the N- and C-lobe sites), and mechanisms for the uptake and release of both metal ions and synergistic anions are discussed.

Uptake and release of iron from human transferrin.
TLDR
In the human, iron loading of transferrin may be considered essentially random, as evaluated by in vitro-added 50Fe and in vivo iron distribution in normal subjects, gave similar results.
Simultaneous multiple element detection by particle beam/hollow cathode-optical emission spectroscopy as a tool for metallomic studies: determinations of metal binding with apo-transferrin.
TLDR
There is clear competition between and Fe(3+) and Zn(2%) for binding in the C-terminus lobe of Tf, while Ni(2+) binds within the N- terminus lobe, and a different mode from the others is indeed observed, and is consistent with conjecture on the Pt(2+ mechanisms.
Separation and determination of iron-containing proteins via liquid chromatography-particle beam/hollow cathode-optical emission spectroscopy.
TLDR
Optical emission detection of the liquid chromatography separations of the iron-containing metalloproteins demonstrates the feasibility of the PB/HC-OES system as a simple element-specific detector for liquid Chromatography.
Intrinsic stoichiometric equilibrium constants for the binding of zinc(II) and copper(II) to the high affinity site of serum albumin.
TLDR
Comparison of binding strengths was possible only through the calculation of an intrinsic stoichiometric binding constant and it was suggested that while both histidyl and carboxyl groups appear to be involved in copper binding, Histidyl residues alone were sufficient for zinc binding.
