Irreversible inhibitors are generally specific for one class of enzyme and do not inactivate all proteins; they do not function by destroying protein structure but by specifically altering the active site of their target. For example, extremes of pH or temperature usually cause denaturation of all protein structure, but this is a non-specific ...
A protein kinase inhibitor (PKI) is a type of enzyme inhibitor that blocks the action of one or more protein kinases. [1] Protein kinases are enzymes that phosphorylate (add a phosphate, or PO 4, group) to a protein and can modulate its function. [2] The phosphate groups are usually added to serine, threonine, or tyrosine amino acids on the
To carry out gene expression, a cell must control the coiling and uncoiling of DNA around histones.This is accomplished with the assistance of histone acetyl transferases (HAT), which acetylate the lysine residues in core histones leading to a less compact and more transcriptionally active euchromatin, and, on the converse, the actions of histone deacetylases (HDAC), which remove the acetyl ...
It is proposed that the drug functions as a competitive inhibitor. Thus, at high concentrations, ATP outcompetes the drug. [7] One limitation of traditional coumarins is gyrB ability to confer antibiotic resistance due to mutations and as a result decrease the inhibitor's ability to bind and induce cell death. [48] [53]
Image illustrates DNA, RNA, and protein synthesis. The first two are nucleic acids. A nucleic acid inhibitor is a type of antibacterial that acts by inhibiting the production of nucleic acids. There are two major classes: DNA inhibitors and RNA inhibitors. [1] The antifungal flucytosine acts in a similar manner.
In response to decreased tetrahydrofolate (THF), the cell begins to transcribe more DHF reductase, the enzyme that reduces DHF to THF. Because methotrexate is a competitive inhibitor of DHF reductase, increased concentrations of DHF reductase can overcome the drugs inhibition. Many new drugs are under development to reduce antifolate drug ...

PARP inhibitors are a call of drugs that are a group of pharmacological inhibitors of the enzyme poly ADP ribose polymerase (PARP), which plays a role in repairing DNA in damaged cells. Medical uses of these drugs include the treatment of heritable cancers . [ 1 ]
