The bovine lactoferrin region responsible for binding to bifidobacteria cell surface protein
Bovine lactoferrin (bLf) is a multifunctional iron-binding glycoprotein secreted mainly in milk and other secretory fluids. Bovine lactoferrin is reported to promote the growth of bifidobacteria and binding of bLf to bifidobacteria cell is thought to be involved. After separation of bLf half molecule and extraction of surface proteins from bifidobacteria, binding profiles were observed by immun...
متن کاملTwo outer membrane proteins are bovine lactoferrin-binding proteins in Mannheimia haemolytica A1
Mannheimia haemolytica is a Gram negative bacterium that is part of the bovine respiratory disease, which causes important economic losses in the livestock industry. In the present work, the interaction between M. haemolytica A1 and bovine lactoferrin (BLf) was studied. This iron-chelating glycoprotein is part of the mammalian innate-immune system and is present in milk and mucosal secretions; ...
متن کاملThermodynamic Analysis for Cationic Surfactants Binding to Bovine Serum Albumin
In the present study, the binding isotherms for interaction of a homologous series of n-alkyltrimethyl ammonium bromides with bovine serum albumin (BSA) have been analyzed on basis of intrinsic thermodynamic quantities. In this regards, the intrinsic Gibbs free energy of binding, AGb(i,)„ has been estimated at various surfactant concentrations and its trend of variation for both binding sets ha...
متن کاملGrowth promotion and cell binding ability of bovine lactoferrin to Bifidobacterium longum.
Lactoferrin, a major whey protein of human milk, is considered as growth promoter for bifidobacteria, the predominant microorganisms of human intestine. In the present study, in vitro growth promotion and cell binding ability of bovine lactoferrin to several strains of Bifidobacterium longum have been demonstrated. A dose-dependent as well as strain-dependent growth promotion effect by lactofer...
متن کاملLactoferrin-binding proteins in Shigella flexneri.
The ability of Shigella flexneri to interact with lactoferrin (Lf) was examined with a 125I-labeled protein-binding assay. The percent binding of human lactoferrin (HLf) and bovine lactoferrin (BLf) to 45 S. flexneri strains was 19 +/- 3 and 21 +/- 3 (mean +/- standard error of the mean), respectively. 125I-labeled HLf and BLf binding to strain M90T reached an equilibrium within 2 h. Unlabeled ...
