Isoenzymes of an acyltransferase from rabbit mammary gland: Solubilization of the micelle-specific species with Triton X-100

The micelle-specific palmityl-CoA: monopalmityl-sn-glycerol 3-phosphate palmityltransferase isoenzyme from lactating rabbit mammary gland microsomes is selectively solubilized in Triton X-100 but not Tween 80. Both detergents inactivate the monomer-specific isoenzyme. The possibility that, $\text{in}$$\text{vivo}$, physiological surfactants regulate the relative activities of these two isoenzymes is discussed.
