title: Membrane lipid environment of carp brain and liver mitochondrial monoamine oxidase.
abstract: Delipidation of carp liver mitochondria by treatment with methyl ethyl ketone (MEK) or Triton X-100 and then perchlorate greatly reduced MAO activities. Treatment with only Triton X-100 resulted in less reduction in activity. The Km values of the remaining activities were similar regardless of these treatments. The sensitivities towards clorgyline and l-deprenyl of the remaining activity in the Triton X-100-treated residue and the phospholipase C-treated carp brain mitochondria were found to be unchanged, but those of the activity remaining in the MEK-treated residue were similarly decreased. No evidence was obtained suggesting conversion of carp MAO to either MAO-A or MAO-B by the modification of the mitochondrial lipid environment by the treatments employed.
