| Application: | Phosvitin from egg yolk has been used: • as a control protein for immobilization on-chip for deep purple protein staining methods for monitoring post-translation modifications • as a substrate for casein kinase Iε in in vitro casein kinase assay • as a standard in gel filtration chromatography (GFC) and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) for quantification of phosvitin from egg extracts • for immobilization onto Layer-by-Layer (LbL) for Fourier transform infrared spectroscopy-attenuated total reflectance (FTIR-ATR) studies |
| Biochem/physiol Actions: | Phosvitin fed to rats by adding egg yolk to their food resulted in decreased absorption of magnesium, iron and calcium but not of phosphorus. |
| Biochem/physiol Actions: | Phosvitin from egg yolk is a calcium chelator and binds to iron present in the yolk. The metal-binding functionality is exploited in mineral-binding bioactive peptide production. It is a nutraceutical and has potential for phosphopeptides production. |
| General description: | Phosvitin from egg yolk is a polyanionic phosphoserine rich protein. This phosphoglycoprotein comprises α-helices and β-sheets structural elements, which are poorly organized due to the presence of phosphoserine. It represents about 11% of yolk proteins and is hydrophilic. |
| Other Notes: | A phosophoprotein containing 8-10% phosphorus. Molar N/P ratio approx. 2.7. |
