Presence and characterization of acetylcholinesterase in brush-border and basolateral membranes of rabbit enterocytes.
Acetylcholinesterase is found in the brush-border and basolateral membranes purified from rabbit enterocytes. The sedimentation coefficients of the enzymes solubilized from two types of membrane are identical (5.5 +/- 0.2 S) and the apparent molecular weights are not significantly different (154 000 +/- 8000 for the brush-border and 145 000 +/- 8000 for the basolateral membrane enzyme). These results suggest a unique G2 molecular form for acetylcholinesterase from brush-border as well as from basolateral membranes.
