Manganese and Iron Binding to Human Transferrin
The characteristics of manganese and iron binding to human apotransferrin (apo-tf) have been investigated and compared in this study. Both metal ions were taken up by human apo-tf and formed complexes, with the maximum absorbances observed at 410 and 340 nm for manganese-transferrin (Mn-tf) and 465 nm for iron-transferrin (Fe-tf). Addition of manganese (1.5 µg/ml) to the reaction mixture contai...

متن کاملTight-binding theory of molecules and solids
A general tight-binding analysis is described which differs from traditional methods in that 1) analytical forms are derived and utilized for obtaining the coupling parameters, and 2) the calculation of electronic-state energies is simplified sufficiently that they also can be obtained analytically. With these two features it becomes possible to write formulae for a wide range of bonding, diele...
متن کاملMicrobial formation of manganese oxides.
Microbial manganese oxidation was demonstrated at high Mn concentrations (5 g/liter) in bacterial cultures in the presence of a microalga. The structure of the oxide produced varied depending on the bacterial strain and mode of culture. A nonaxenic, acid-tolerant microalga, a Chlamydomonas sp., was found to mediate formation of manganite (gamma-MnOOH). Bacteria isolated from associations with c...
