Choline acetyltransferase from rat brain.
The localization, purification, and some enzymatic properties of choline acetyltransferase from rat brain were studied. Most assays were performed with a specific radiometric micromethod. Solubilization of the enzyme was examined after homogenization of cerebral cortices by means which disintegrate nerve endings. In isotonic KC1 the enzyme was recovered in solution. In more dilute KC1 the enzym...
متن کاملMultiple forms of choline acetyltransferase in several species demonstrated by isoelectric focusing.
1. The behaviour of choline acetyltransferase from pigeon, guinea-pig, rat and cat brain on isoelectric focusing was studied. 2. Choline acetyltransferase from pigeon and guinea-pig brain showed single peaks with isoelectric points at pH6.6 and 6.8 respectively. Only one molecular form of the enzyme was therefore detected in these species. 3. Three peaks of choline acetyltransferase activities ...
متن کاملMolecular weight determinations of soluble and membrane-bound fractions of choline O-acetyltransferase in rat brain.
Three fractions of choline O-acetyltransferase (ChAT) (EC 2.3.1.6) were solubilized from a nerve ending fraction of rat forebrain using three sequential washes of an increasingly chaotrophic nature (100 mM sodium phosphate, pH 7.4; 500 mM NaCl; 2% Triton DN-65) as previously described (Benishin, C.G., and P.T. Carroll (1983) J. Neurochem. 41: 1030-1039). The molecular weights of the soluble (Na...
متن کاملDeprenyl increases synaptophysin and choline acetyltransferase in rat after sciatic nerve axotomy
Neuroprotective effect of deprenyl on motoneurons of spinal cord after axotomy of peripheral nerves such as sciatic has been well established. Deprenyl is an inhibitor of monoamine oxidase type-B (MAO-B). The main function of this agent is the release of neurotransmitters from pre-synaptic terminals. Acetylcholine is a neurotransmitter that is synthesized by choline acetyltransferase (ChAT) and...
