Phosvitin from egg yolk

半岛bd体育手机客户端 说明

一般描述

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.

应用

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 I_εinin vitrocasein 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

生化/生理作用

Phosvitin fed to rats by adding egg yolk to their food resulted in decreased absorption of magnesium, iron and calcium but not of phosphorus.
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.

其他说明

A phosophoprotein containing 8-10% phosphorus. Molar N/P ratio approx. 2.7.
