Aminopterin works as an enzyme inhibitor by competing for the folate binding site of the enzyme dihydrofolate reductase.

Roundup uses an enzyme inhibitor, glyphosate, to block one of the steps of the shikimate pathway.

He and his colleagues are attempting to create enzyme inhibitors by working backward from the enzyme.

Enzyme inhibitors also occur naturally and are involved in the regulation of metabolism.

Other cellular enzyme inhibitors are proteins that specifically bind to and inhibit an enzyme target.

So buff twice a week with a body scrub, and slough away dullness on your face with a gentle exfoliator containing fruit enzymes such as papain (from papaya).

This clock-stopping facial uses super-strong glycolic acid (10-40 per cent depending on your skin type) and fruit enzymes to nibble away at dull, dead skin.

Fruit enzymes are the key, allowing exfoliation at a biochemical level rather than by scouring your face off.

Two hand-held vibrating devices are used to gently graze my face, emitting sonic pulses to activate the fruit enzymes and enhance the penetration of ingredients.

Then there's yer fruit enzymes, which exist in things such as papaya.

In contrast, when measured using peptide substrates, denaturants inhibit the enzyme.

However, mutagenesis studies have indicated that these residues are not individually essential for catalysis, as only mutations of two or more residues inhibit the enzyme.

Other cellular enzyme inhibitors are proteins that specifically bind to and inhibit an enzyme target.

Organophosphates inhibit an enzyme called acetylcholinesterase, causing a buildup of acetylcholine, excessive stimulation of all types of cholinergic neurons, and a wide range of symptoms.

These chemical compounds inhibit the enzyme acetylcholinesterase, preventing the normal breakdown of neurotransmitter acetylcholine.

Repeat exposure results in accumulation and increasing inhibition of the key enzyme acetylcholinesterase.

Biochemists come to know sections of this vast interplay of reactions intimately, often spending a professional lifetime describing a single key enzyme.

Research literature suggests that over-activity of glycogen synthase, the key enzyme in synthesizing glycogen, can lead to the formation of polyglucosans.

Further work on nucleotide metabolism allowed him to identify nucleoside phosphorylase, a key enzyme in nucleotide salvage pathways.

During growth on methanol key enzymes of the methanol metabolism are present in high amounts.

As many as 16 per cent of people are 'lactose intolerant' - they lack the enzyme necessary to break down milk.

People who lack this enzyme, like me, and who consume milk, quickly learn the meaning of lactose intolerance.

They lack the enzyme — lactase — to digest milk properly and so a dairy diet leaves them feeling ill and bloated.

Humans lack the enzyme chitinase, so can not fully digest raw mushrooms or their derivatives, and the digestive process works too fast for the stomach acid to take effect.

His body lacked an enzyme that plays a crucial role in metabolism, resulting in an accumulation of toxic products in his organs and tissues.

Research suggests that silymarin, the active compound in milk thistle seeds, increases production of glutathione, a vital detoxing liver enzyme.

They lower cholesterol in the blood by limiting a liver enzyme which regulates its production.

The elevation of liver enzyme in the blood helps to establish a diagnosis.

Other reversible early effects noted were peripheral neuropathy and liver enzyme induction.

It has liver enzyme inducing effects similar to those of phenobarbital but much weaker.

Enzyme replacement therapy involves replacing a missing enzyme in individuals who are deficient or lack the particular enzyme in question.

An experiment was then carried out to see whether an injection of the missing enzyme into the hips would help the range of motion and pain.

Although the missing enzyme can be manufactured and given intravenously, it can not penetrate the bloodbrain barrier and therefore can not treat the neurological manifestations of the disease.

It contains ectoin - a natural enzyme that protects skin.

This new enzyme catalyzes a chemical reaction not known to be catalyzed by any natural enzyme.

I chose to create capsules filled with natural enzymes usually found in liver cells to help the body process the alcohol faster.

Reduce the work the pancreas has to do: ask your vet about enzyme supplements, probiotics in the food and a raw diet (full of natural enzymes).

Her research harnesses the power of natural enzymes to help image protein function in living cells.

These bacteria produce an enzyme known as glucosyltransferase.

Blowfly maggots produce an enzyme that confers resistance to organochloride insecticides.

They were looking for a gene that produces an enzyme called deiodonase-2, which helps to make thyroid hormone available within cells.

Well-trained muscle produces an enzyme that purges the body of harmful substances.

Bacteria from the gum disease gingivitis produces an enzyme which destroys brain nerve cells, leading to memory loss.

Feather waste has been used in a number of industrial applications as a medium for culturing microbes, biodegradeable polymers, and production of enzymes.

The composition of the growth medium guides the microorganism's metabolism towards the production of enzymes that release bio-available single molecules such as sugars or amino acids by carving out macromolecules.

The disease progresses in concert with formation of granulation tissue at the edges of the synovial lining (pannus) with extensive angiogenesis and production of enzymes that cause tissue damage.

It may secrete an enzyme to soften the wood before starting to dig with its foot.

Our digestive systems are perfectly capable of secreting enzymes that break down protein and carbohydrate simultaneously.

Normally they secrete enzymes onto their prey to digest them outside the body and then consume what's left as a kind of soup.

First, the hyphae secrete enzymes onto or into the food source, which break down biological polymers into smaller units such as monomers.

The plant then secretes enzymes which dissolve the insects and release the nutrients, which are then absorbed by the plant.
