Bovine milk fat globule membrane proteome.
Milk fat globule membranes (MFGM) were isolated from the milk of mid-lactation Holstein cows. The purified MFGM were fractionated using 1-dimensional SDS gels. Tryptic peptides from gel slices were further fractionated on a micro-capillary high performance liquid chromatograph connected to a nanospray-tandem mass spectrometer. Analysis of the data resulted in 120 proteins being identified by tw...
متن کاملBiochemical and Morphological Comparison of Plasma Membrane and Milk Fat Globule Membrane from Bovine Mammary Gland
Purified plasma membrane fractions from lactating bovine mammary glands and membranes of milk fat globules from the same source were similar in distribution and fatty acid composition of phospholipids. The sphingomyelin content of the phospholipid fraction of both membranes was higher than in these fractions from other cell components, beta-carotene, a constituent characteristic of milk fat, wa...
متن کاملPreparation of monoclonal antibodies to xanthine oxidase and other proteins of bovine milk-fat-globule membrane.
Nine hybridomas secreting monoclonal antibody to proteins of bovine milk-fat-globule membrane were isolated. All nine cell lines continued to secrete monoclonal antibody after serial transfer in culture and after passage as solid tumours in Balb/cJ mice. Four of the cell lines secreted monoclonal antibody specific for xanthine oxidase, one of the major proteins of milk-fat-globule membrane.
متن کاملAssociation of xanthine oxidase with the bovine milk-fat-globule membrane.
1. The catalytic properties of xanthine oxidase in bovine milk (EC 1.2.3.2) are dependent on the state of the enzyme, i.e. whether free or bound to the fat-globule membrane. Oxidase activity of the membrane-bound enzyme towards NADH is enhanced relative to that towards xanthine. This reflects a change in the relative K(m) values and enables the ratio of xanthine to NADH oxidase activities (X/N)...
متن کاملIsolation and structural characterization of alkali-labile oligosaccharides from bovine milk-fat-globule membrane.
Treatment of sialoglycopeptides derived from bovine milk-fat-globule membrane with alkaline borohydride released a reduced oligosaccharide fraction from which a tetrasaccharide and two trisaccharides were isolated. Periodate-oxidation studies coupled with methylation analysis and g.l.c.-mass spectrometry established their structures as: N-acetylneuraminyl-(2 leads to 3)-beta-D-galactopyranosyl-...
