Therefore, the activity of the enzyme increases when the cellular ATP/AMP ratio is lowered. Glycolysis is thus stimulated when energy charge falls. PFK1 has two sites with different affinities for ATP which is both a substrate and an inhibitor. [3] PFK1 is also inhibited by low pH levels which augment the inhibitory effect of ATP.
In enzymology, 1-phosphofructokinase (EC 2.7.1.56) is an enzyme that catalyzes the chemical reaction. ATP + D-fructose 1-phosphate → ADP + D-fructose 1,6-bisphosphate. Thus, the two substrates of this enzyme are ATP and D-fructose 1-phosphate, whereas its two products are ADP and D-fructose 1,6-bisphosphate.
Phenelzine, sold under the brand name Nardil among others, is a non-selective and irreversible monoamine oxidase inhibitor (MAOI) of the hydrazine family which is primarily used as an antidepressant and anxiolytic to treat depression and anxiety. [3]
The enzyme-catalysed transfer of a phosphoryl group from ATP is an important reaction in a wide variety of biological processes. [1] Phosphofructokinase catalyses the phosphorylation of fructose-6-phosphate to fructose-1,6-bisphosphate , a key regulatory step in the glycolytic pathway .
Canagliflozin, sold under the brand name Invokana among others, is a medication used to treat type 2 diabetes. [3] It is used together with exercise and diet. [3] It is not recommended in type 1 diabetes. [3] It is taken by mouth. [3] Common side effects include vaginal yeast infections, nausea, constipation, and urinary tract infections. [3]
An enzyme inhibitor stops ("inhibits") this process, either by binding to the enzyme's active site (thus preventing the substrate itself from binding) or by binding to another site on the enzyme such that the enzyme's catalysis of the reaction is blocked. Enzyme inhibitors may bind reversibly or irreversibly.

Cenobamate induces the enzymes CYP3A4 and CYP2B6 and can therefore decrease blood concentrations of drugs that are metabolized by these enzymes (for example midazolam and bupropion, respectively). Conversely, it inhibits the enzyme CYP2C19, potentially increasing concentrations of drugs metabolized by this enzyme (for example omeprazole). [13] [14]
