Its enzymatic activity was usually assayed by measuring ... new techniques as we isolated and characterized these new enzyme inhibitors. However, our synthetic expertise was an invaluable tool ...

Genes for some of the enzymes in a cell are expressed so that the enzymes are always present. Influencing their activity can control their rates of reaction. Different chemicals can influence ...

Indeed, some but not all nucleoside analogs can inhibit telomerase activity 52. The results presented here indicate that specific, potent inhibitors of the hTERT enzyme are likely to be very ...

The presence of an endogenous oxidant, such as hydroperoxide, in the incubation milieu is critical for the measurement of COX activity ... inhibition of COX in vitroare the source of the enzyme ...

Medically reviewed by Danielle Weiss, MD Angiotensin-converting enzyme (ACE) inhibitors are oral medications that lower blood ...

Enzymes are primarily proteins, although some RNA molecules called ribozymes also exhibit enzymatic activity. Enzymes are biological catalysts that lower the activation energy of chemical reactions, ...
