Exempel på coenzyme

• Glutathione, a tripeptide thiol found in all cells, functions in metabolism as a coenzyme for a number of enzymes, in amino acid transport and in protecting cells against oxidative stress.

• This "cis-trans" -isomerase contains glutathione as a coenzyme.

• They may also be less tightly bound to enzyme catalysts as coenzymes, detachable molecules that function to carry chemical groups or electrons between molecules.

• They are natural toxins that cause slow binding inhibition by interfering with the coenzyme pyridoxal phosphate.

• Cofactors are ions or coenzymes necessary for enzyme activity.

• The term coenzyme refers specifically to enzymes and, as such, to the functional properties of a protein.

• Organic cofactors are sometimes further divided into "coenzymes" and "prosthetic groups".

• Pyridoxal phosphate generally serves as a coenzyme for many reactions and can help facilitate decarboxylation, transamination, racemization, elimination, replacement and beta-group interconversion reactions.

• This discovery was used to re-engineer coenzyme specificities of enzymes.

• Metabolism and coenzyme function of the vitamin suggest a distinctive function for thiamin within the nervous system.

• This gives them an advantage over other enzymes that can only use a single form of the coenzyme.

• The active sight is found in each subunit between the two distinct // globular domains, the substrate binding domain and the coenzyme binding domain.

• This coenzyme contains electrons that have a high transfer potential; in other words, they will release a large amount of energy upon oxidation.

• In general, the electron donor is any of a wide variety of flavoenzymes and their coenzymes.

• When the enzyme is inhibited by methotrexate, the cellular levels of folate coenzymes diminish.
