Choline acetyltransferase. Inhibition by thiol reagents.
Choline acetyltransferase (EC 2.3.1.6) catalyzes the reversible transfer of the acetyl group from acetyl coenzyme A to choline. Previous studies are consistent with the idea that an active site sulfhydryl group reacts with acetyl coenzyme A to form an acetyl-thioenzyme intermediate and coenzyme A (ROSKOSKI, R., JR. (1973) Biochemistry 12, 3709). Choline then reacts with the acetyl-enzyme to for...
متن کاملInhibition of choline acetyltransferase by monoclonal antibodies.
Four monoclonal antibodies were obtained to rat brain choline acetyltransferase (CAT). The enzyme was purified 95,000-fold from rat brain by precipitation with acetic acid at pH 4.5, fractionation with 40 to 60% (NH4)2SO4, CM-Sephadex chromatography, and affinity column chromatography on agarose-hexane-coenzyme A. The enzyme preparation was applied to the affinity column in the presence of 10 m...
متن کاملCholine 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 کاملCholine transporter 1 maintains cholinergic function in choline acetyltransferase haploinsufficiency.
Choline acetyltransferase (ChAT), the enzyme that synthesizes the neurotransmitter acetylcholine (ACh), is thought to be present in kinetic excess in cholinergic neurons. The rate-limiting factor in ACh production is the provision of choline to ChAT. Cholinergic neurons are relatively unique in their expression of the choline transporter 1 (CHT1), which exhibits high-affinity for choline and ca...
متن کاملCholine acetyltransferase: reversible inhibition by bromoacetyl coenzyme A and bromoacetylcholine.
Choline acetyltransferase (EC 2.3.1.6) catalyzes the following reversible reaction: acetyl coenzyme A + choline acetylcholine + coenzyme A. Bromoacetyl-CoA and bromoacetylcholine are potent inhibitors of the bovine brain enzyme. Although the enzyme is inactive immediately following Sephadex gel filtration to remove unreacted inhibitor, enzyme activity returns to normal in 1 day at 0". When the ...
