title: Ability of calf brain synaptic membranes to bind [35S]taurine to their triton X-100 and chloroform extracts.
abstract: A protein fraction containing reducing sugars was prepared from calf brain synaptic membranes with 0.5% Triton X-100, and another fraction containing bound phosphorus with a 2 : 1 chloroform--methanol mixture. Both protein fractions bound small amounts of [35S]taurine, the first fraction about 25 pmol/g protein and the second about 220 pmol/g protein. The Triton X-100 extract represented 13.8% of the membrane proteins, but the chloroform--methanol extract only 0.9%. The binding of taurine to the Trition X-100 extract was temperature sensitive, but was only slightly inhibited by hypotaurine and beta-alanine.
