Study of a hydrophobic site on bovine alpha-lactalbumin by labeling with [125I]-TID

J C Van Ceunebroeck et al. Biochem Biophys Res Commun. .

Abstract

The hydrophobic, photoreactive probe 3-(trifluoromethyl)-3-(m-[125I]iodophenyl) diazirine ([125I]TID) labels apo-bovine alpha-lactalbumin but much less his Ca2+-form. The labeling of the apo-form is strong at protein concentrations of 0.5 mg ml-1 and increases with increasing concentration. Furthermore, increasing concentrations of NaCl, decrease the labeling of apo-alpha-lactalbumin with [125I]TID.
