Enzyme in a sentence

A molecule that fits the active site of an enzyme, but cannot be released by the enzyme, inactivates the enzyme.

At the maximum reaction rate (V max ) of the enzyme, all the enzyme active sites are bound to substrate, and the amount of ES complex is the same as the total amount of enzyme.

For example, if you have a genetic mutation where one specific enzyme in your body is messed up, it might be as simple as creating a biotech version of that enzyme and giving you daily/weekly injections to replace the fucked up one with a shiny new one.

The next step is to start taking patients off the weekly enzyme treatments they’ve been receiving to see if the gene therapy has changed their bodies so they make enough of the enzyme themselves.

Enzyme activity can be affected by other molecules: inhibitors are molecules that decrease enzyme activity, and activators are molecules that increase activity.

First acylation of the substrate to form an acyl-enzyme intermediate and then deacylation in order to return the enzyme to its original state.

If this enzyme reaches a "hemimethylated" portion of DNA (where 5-methylcytosine is in only one of the two DNA strands) the enzyme will methylate the other half.

In the 1960s, it was shown in work done in the laboratories of Werner Arber and Matthew Meselson that the restriction is caused by an enzymatic cleavage of the phage DNA, and the enzyme involved was therefore termed a restriction enzyme.

Reducing enzyme activity can disable a pathogen or correct an incorrectly function system; as such, many enzyme inhibitors are developed to be used as drugs for the general public.

That compound is converted to dihydroxyacetone phosphate by the enzyme triose phosphate isomerase, which is a catalytically perfect enzyme; its rate is so fast that the reaction can be assumed to be in equilibrium.

The necessary contacts between an enzyme and its substrates (proteins) are created because the enzyme folds in such a way as to form a crevice into which the substrate fits; the crevice also contains the catalytic groups.

These molecules then cause a change in the conformation or dynamics of the enzyme that is transduced to the active site and thus affects the reaction rate of the enzyme. citation In this way, allosteric interactions can either inhibit or activate enzymes.

This covalent acyl-enzyme intermediate is then hydrolysed by activated water to complete catalysis by releasing the second half of the product and regenerating the free enzyme.

This enzyme is found in all forms of life and functions in the same way in both prokaryotes and eukaryotes. citation The enzyme uses the energy stored in a proton gradient across a membrane to drive the synthesis of ATP from ADP and phosphate (P i ).

This is then transferred to E1's active-site cysteine residue in concert with the adenylylation of a second ubiquitin. citation This adenylylated ubiquitin is then transferred to a cysteine of a second enzyme, ubiquitin-conjugating enzyme (E2).

This reaction occurs due to the enzyme hexokinase, an enzyme that helps phosphorylate many six-membered ring structures.

When enzyme catalysed (solid line), the enzyme binds the substrates (ES), then stabilizes the transition state (ES ‡ ) to reduce the activation energy required to produce products (EP) which are finally released.

Adding long-chain fatty acids can thicken cell membranes and alter the activity of a key enzyme, as LMU scientists have demonstrated in cell cultures.

B Vitamins Can Reduce Body Weight Gain by Increasing Metabolism-related Enzyme Activities in Rats Fed on a High-Fat Diet.

Calcium involves various bodily functions, including blood clotting, enzyme activity, and hormone secretion.
