We have some paraffin embedded brain tissues that we are trying to stain with an AchE (acetylcholinesterase) protocol. Acetylcholinesterase E.C. ACHE is thought to be involved in the pathology of Alzheimer's disease (AD) by accelerating the assembly of Abeta peptides into fibrillar species through forming complexes with Abeta via the peripheral anionic site on ACHE. Torpedo california AChE (PDB code 2ace) (, (. Acetylcholinesterase definition is - an enzyme that occurs chiefly in cholinergic nerve endings and promotes the hydrolysis of acetylcholine : cholinesterase. Durch Hemmung der Acetylcholinesterase steht im synaptischen Spalt vermehrt Acetylcholin zur Verfügung, das an seine nikotinergen und muskarinergen Acetylcholin-Rezeptoren binden kann. From Proteopedia. Acetylcholinesterase is present at all cholinergic junctions. The enzyme decimates the transmission at cholinergic synapses by hydrolyzing the neurotransmitter acetylcholine. Acetylcholinesterase (også kendt som AChE) er et enzym, der katalyserer nedbrydningen af acetylcholin, der fungerer som neurotransmitter.. Acetylcholinesterase hydrolyserer acetylcholin til cholin og eddikesyre ved motoriske endeplader og hjernens cholinerge synapser og afslutter således signaltransmissionen. Acet y lcholinesterase-Hemmer. proteopedia link proteopedia link. Det findes også på røde blodlegemers membraner, hvor det udgør Yt … Acetylcholinesterase inaktiviert die Acetylcholin-Moleküle durch Hydrolyse. Die Acetylcholinesterase ist eines der schnellsten Enzyme überhaupt (diffusionskontrolliert, siehe Enzymkinetik und Diffusion).
