일반 설명
Acetylcholinesterase (AChE) is a serine hydrolase, which belongs to the carboxyl esterase family of enzymes. AChE is localised at neuromuscular junctions and cholinergic brain synapses.
애플리케이션
Acetylcholinesterase human has been used:
- as a standard protein to measure protein levels acetylcholinesterase AChE-R and AChE-S
- to stimulate human fibroblasts
- to study its in vitro catalytic activity and to determine the effects of metals, H2O2 and OH radicals on the activity
생화학적/생리학적 작용
Acetylcholinesterase (AChE) is regarded as a biomarker in neurotoxicity. It is a modulator of nitric oxide signal transduction pathway and marker of membrane integrity and aging. AChE, hydrolyzes choline esters. It terminates the impulse transmission at cholinergic synapses. AChE does this by rapid hydrolysis of the neurotransmitter acetylcholine (ACh) to acetate and choline. AChE inhibitors prevent the cholinesterase enzyme from breaking down ACh and increases the level and duration of the neurotransmitter action.
Major degradative enzyme for acetylcholine in vivo. Converts acetylcholine + H2O to choline + acetic acid.
단위 정의
One unit will hydrolyze 1.0 μmole of acetylthiocholine to thiocholine and acetate per minute at pH 8.0 at 37 °C.
물리적 형태
This product is supplied as a lyophilized powder. Lyophilized from 0.22 μm filtered solution in 50mM phosphate buffer pH8.
분석 메모
The activity obtained using acetylcholine as substrate is 30-100 times that obtained with butyrylcholine, using acetylcholinesterase from electric eel.

Despite extensive efforts in the development of drugs for complex neurodegenerative diseases, treatment often remains challenging or ineffective, and hence new treatment strategies are necessary. One approach is the design of multi-target drugs, which can potentially address the complex nature
