Iron-dependent binding of 8-anilinonaphthalene-1-sulphonate by both lactoferrin and transferrin.
نویسندگان
چکیده
Fluorescence of 8-anilinonaphthalene-1-sulphonate is enhanced by both lactoferrin and transferrin. The enhancement is relatively low between pH 4 and 8, and high at below pH 4. At physiological pH the fluorescence enhancement is higher with the iron-deprived than with the iron-saturated proteins. Binding of iron by lactoferrin is associated with lowering affinity for the dye.

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 کاملStudy of the Binding of Iron and Indium to Human Serum Apo-Transferrin
Indium is a heavy metal belonging to group IIIa. It is believed that indium may interfere with iron metabolism from the sites of absorption, transportation, utilization and storage in the cells. The present investigation was established to study and compare the binding of iron and indium to human apo-transferrin (apo-tf). Pure human apo-tf was used and the binding activity of iron and indium, a...
متن کاملLactoferrin binding by leukemia cell lines.
Monocytes and macrophages have receptors for the iron-binding protein lactoferrin. Lactoferrin acts as a potent inhibitor of granulocyte-macrophage colony stimulating factor production when it binds to these cells. Using a rosette assay and immunofluorescence, we have shown that cultured leukemia cells, including the human erythroid leukemia cell line K562, also have lactoferrin binding sites. ...
متن کاملIn silico investigation of lactoferrin protein characterizations for the prediction of anti-microbial properties
Lactoferrin (Lf) is an iron-binding multi-functional glycoprotein which has numerous physiological functions such as iron transportation, anti-microbial activity and immune response. In this study, different in silico approaches were exploited to investigate Lf protein properties in a number of mammalian species. Results showed that the iron-binding site, DNA and RNA-binding sites, signal pepti...
