Description générale
Molecular Weight: 280 kDa
Isoelectric Point: 5.5
Extinction Coefficient: E1% = 18.0 (280 nm)
Acetylcholinesterase from Electrophorus electricus is a tetramer composed of 4 equal subunits of 70 kDa each. Each subunit contains one active site. The enzyme is a glycoprotein containing hexosamines.

Application
Acetylcholinesterase from Electrophorus electricus (electric eel) has been used:
- in acetylcholinesterase activity assay
- to study its effects on Xenopus embryonic hippocampal cells
- to study the effect of acetylcholine inhibitors on development and plasticity
Actions biochimiques/physiologiques
Acetylcholinesterase (AChE) exhibits its activity against acetylcholine in the neuromuscular junctions and synaptic cleft of cholinergic neurons. It participates in the nitric oxide signaling pathway.
Major degradative enzyme for acetylcholine in vivo. Converts acetylcholine + H2O to choline + acetic acid.
Attention
For dilute solutions (<1 mg/ml), add 1 mg/ml BSA to stabilize. Solutions containing at least 1 mg protein/ml in dilute neutral phosphate buffer are stable at least 6 months refrigerated.
Définition de l'unité
One unit will hydrolyze 1.0 μmole of acetylcholine to choline and acetate per min at pH 8.0 at 37 °C.
Forme physique
Lyophilized powder containing Tris buffer salts
Remarque sur l'analyse
The activity obtained using acetylcholine as substrate is 30-100 times that obtained with butyrylcholine, using acetylcholinesterase from electric eel.

Over the last decades, antifouling coatings containing biocidal compounds as active ingredients were used to prevent biofouling, and eco-friendly alternatives are needed. Previous research from our group showed that polymethoxylated chalcones and glycosylated flavones obtained by synthesis displayed antifouling activity

Here we show that chronic application of low concentrations (0.01-0.05 U/ml) or a single application of 1-5 U/ml acetylcholinesterase (AChE) promotes the extension of neuronal processes, synapse formation, and alpha-amino-3-hydroxy-5-methylisoxazolepropionate receptor (AMPAR) surface expression in both embryonic and postnatal hippocampal

A novel, integrated experimental and modeling framework was applied to an inhibition-based bi-enzyme (IBE) electrochemical biosensor to detect acetylcholinesterase (AChE) inhibitors that may trigger neurological diseases. The biosensor was fabricated by co-immobilizing AChE and tyrosinase (Tyr) on the gold working
