Cholineesterase is enzyme that hydrolyses acetylcholine .
Cholinesterase inhibitors are drugs that block the activity of an enzyme in the brain called cholinesterase. Cholinesterase breaks apart the neurotransmitter acetylcholine, which is vital for the transmission of nerve impulses.
It's an enzyme that breaks down the neurotransmitter acetylcholine. Basically, neurotransmitters are necessary for nerves to transmit impulses and messages throughout the body. Acetylcholine is used specifically to transmit sensory messages. Sometimes, the body produces so much acetylcholine that it becomes an annoyance. In these cases, cholinesterase is responsible for balancing out the production of acetylcholine by destroying it.
Electrical switching centers, called 'synapses' are found throughout the nervous systems of humans, other vertebrates, and insects. Muscles, glands, and nerve fibers called 'neurons' are stimulated or inhibited by the constant firing of signals across these synapses. Stimulating signals are usually carried by a chemical called 'acetylcholine' (a-see-till-ko-leen). Stimulating signals are discontinued by a specific type of cholinesterase enzyme, acetylcholinesterase, which breaks down the acetylcholine. These important chemical reactions are usually going on all the time at a very fast rate, with acetylcholine causing stimulation and acetylcholinesterase ending the signal. If cholinesterase-affecting insecticides are present in the synapses, however, this situation is thrown out of balance. The presence of cholinesterase inhibiting chemicals prevents the breakdown of acetylcholine. Acetylcholine can then build up, causing a "jam" in the nervous system. Thus, when a person receives to great an exposure to cholinesterase inhibiting compounds, the body is unable to break down the acetylcholine
Yes, it is an enzyme and all enzymes are proteins.
Nerve agents work by blocking a hormone called cholinesterase. A nerve is basically a pipe. When your body wants to send information down a nerve, it puts a little bit of the hormone acetylcholine into it. When it wants to stop sending, it shoots some cholinesterase down the pipe, and the cholinesterase "turns off" the acetylcholine. (There's more to it than that, but you get the idea.) By stopping cholinesterase from working, your whole body just goes into convulsions and, eventually, you just seize up. Very nasty way to die.

Acetylcholinesterase
The presence of an enzyme called acetylcholinesterasethat degrades acetylcholine is what prevents an accumulation of the neurotransmitter and sustained muscle contraction. Acetylcholinesterase is an enzyme that can be found within the neuromuscular junction. Thus, when a nerve impulse causes the release of acetylcholine at the neuromuscular junction, there is a critical time in which the neurotransmitter can bind to receptors on the muscle before it is degraded.
Ach is reduced by acetylcholine esterase- an enzyme.
Acetylcholine is degraded by acetylcholinesterase
Its degradation by a hydrolytic enzyme on the postsynaptic membrane.
