  • PMID
  • This entry includes ribonuclease N1 (RNase N1), a guanine-specific ribonuclease from fungi [ PMID: 2977130 ], and its related RNases from bacteria, RNase T1 and Sa. (ebi.ac.uk)
  • uracil
  • Guanine, along with adenine and cytosine, is present in both DNA and RNA, whereas thymine is usually seen only in DNA, and uracil only in RNA. (wikipedia.org)
  • 10NH3 + 2CH4 + 4C2H6 + 2H2O → 2C5H8N5O (guanine) + 25H2 A Fischer-Tropsch synthesis can also be used to form guanine, along with adenine, uracil, and thymine. (wikipedia.org)
  • Heating an equimolar gas mixture of CO, H2, and NH3 to 700 °C for 15 to 24 minutes, followed by quick cooling and then sustained reheating to 100 to 200 °C for 16 to 44 hours with an alumina catalyst, yielded guanine and uracil: 10CO + H2 + 10NH3 → 2C5H8N5O (guanine) + 8H2O Another possible abiotic route was explored by quenching a 90% N2-10%CO-H2O gas mixture high-temperature plasma.

  • enzymology
  • In enzymology, a guanine-transporting ATPase (EC 3.6.3.37) is an enzyme that catalyzes the chemical reaction ATP + H2O + guanineout ⇌ {\displaystyle \rightleftharpoons } ADP + phosphate + guaninein The 3 substrates of this enzyme are ATP, H2O, and guanine, whereas its 3 products are ADP, phosphate, and guanine. (wikipedia.org)
  • catalyzes
  • HGPRT is a transferase that catalyzes conversion of hypoxanthine to inosine monophosphate and guanine to guanosine monophosphate. (wikipedia.org)
  • In this role, it catalyzes the reaction between guanine and phosphoribosyl pyrophosphate (PRPP) to form GMP, or between hypoxanthine and phosphoribosyl pyrophosphate (PRPP) to form inosine monophosphate. (wikipedia.org)
  • In the guanine nucleotide pathway, there are 2 enzymes involved in converting IMP to GMP, namely IMP dehydrogenase (IMPD1), which catalyzes the oxidation of IMP to XMP, and GMP synthetase, which catalyzes the amination of XMP to GMP. (wikipedia.org)
  • hydrogen
  • Energetic properties and optimized geometries of 10 radicals and their respective anions derived through hydrogen abstraction from the Watson-Crick guanine-cytosine (G-C) base pair have been studied using reliable theoretical methods. (pnas.org)
  • Guanine has the C-6 carbonyl group that acts as the hydrogen bond acceptor, while a group at N-1 and the amino group at C-2 act as the hydrogen bond donors. (wikipedia.org)
  • produces
  • Facial treatments using the droppings, or guano, from Japanese nightingales have been used in Japan and elsewhere, reportedly because the guanine in the droppings produces a clear, "bright" skin tone that users desire. (wikipedia.org)
  • Structure
  • The Report provides a basic overview of the Guanine Market including definitions, classifications, applications and chain structure. (beforeitsnews.com)
  • Between 1882 and 1906, Fischer determined the structure and also showed that uric acid can be converted to guanine. (wikipedia.org)
  • products
  • In the cosmetics industry, crystalline guanine is used as an additive to various products (e.g., shampoos), where it provides a pearly iridescent effect. (wikipedia.org)
