Cyclic ADP-ribose, frequently abbreviated as cADPR, is a cyclic adenine nucleotide (like cAMP) with two phosphate groups present on 5' OH of the adenosine (like ADP), further connected to another ribose at the 5' position, which, in turn, closes the cycle by glycosidic bonding to the nitrogen 1 (N 1) of the same adenine base (whose position N 9 has the glycosidic bond to the other ribose).
ADP-ribosyltransferase 5 is a protein that in humans is encoded by the ART5 gene. Function. The protein encoded by this gene belongs to the ARG -specific ADP - ribosyltransferase family. Proteins in this family regulate the function of target proteins by attaching ADP -ribose to specific amino acid residues in their target proteins.
(ADP-ribosyl)hydrolase 3 (ARH3) is an enzyme that in humans is encoded by the ADPRHL2 gene (also called ADPRS). This enzyme reverses the proteins’ post-translational addition of ADP-ribose to serine residues as part of the DNA damage response The enzyme is also known to cleave poly(ADP-ribose) polymers, 1''-O-acetyl-ADP-ribose and alpha-NAD +
The transporter is an obligate exchange translocase specific for ATP and ADP. It functions to take up ATP from the eukaryotic cell cytoplasm into the bacterium in exchange for ADP. The ATP/ADP uniporters can also transport inorganic phosphate, but not ribonucleoside and monophosphates, as well as deoxyribonucleotides. [3] [4]
In enzymology, an ADP-specific glucokinase (EC 2.7.1.147) also known as ADP-dependent glucokinase is an enzyme that catalyzes the chemical reaction. ADP + D-glucose AMP + D-glucose 6-phosphate. Thus, the two substrates of this enzyme are ADP and D-glucose, whereas its two products are AMP and D-glucose 6-phosphate.
Glucose-1-phosphate adenylyltransferase. In enzymology, a glucose-1-phosphate adenylyltransferase ( EC 2.7.7.27) is an enzyme that catalyzes the chemical reaction. Thus, the two substrates of this enzyme are ATP and alpha-D- glucose 1-phosphate, whereas its two products are diphosphate and ADP-glucose . This enzyme belongs to the family of ...
Adenosine diphosphate ( ADP) receptor inhibitors are a drug class of antiplatelet agents, used in the treatment of acute coronary syndrome (ACS) or in preventive treatment for patients who are in risk of thromboembolism, myocardial infarction or a stroke. These drugs antagonize the P2Y 12 platelet receptors and therefore prevent the binding of ...
(2) ADP + (6S)-6β-hydroxy-1,4,5,6-tetrahydronicotinamide-adenine dinucleotide phosphate AMP + phosphate + NADPH This enzyme acts equally well on hydrated NADH and hydrated NADPH. References [ edit ]
