Phosphoribosyl-N-formylglycineamidePurinosomeCarbon–carbon bond: A carbon–carbon bond is a covalent bond between two carbon atoms. The most common form is the single bond: a bond composed of two electrons, one from each of the two atoms.Nitrogen deficiencyMG132Nitrile hydratase: In enzymology, nitrile hydratases (NHases; ) are mononuclear iron or non-corrinoid cobalt enzymes that catalyse the hydration of diverse nitriles to their corresponding amidesHECT domain: In molecular biology, the HECT domain is a protein domain found in ubiquitin-protein ligases. The name HECT comes from 'Homologous to the E6-AP Carboxyl Terminus'.Non-homologous end joining: Non-homologous end joining (NHEJ) is a pathway that repairs double-strand breaks in DNA. NHEJ is referred to as "non-homologous" because the break ends are directly ligated without the need for a homologous template, in contrast to homology directed repair, which requires a homologous sequence to guide repair.Cullin: Cullins are a family of hydrophobic proteins providing a scaffold for ubiquitin ligases (E3). All eukaryotes appear to have cullins.Ubiquitin: Ubiquitin is a small (8.5 kDa) regulatory protein that has been found in almost all tissues (ubiquitously) of eukaryotic organisms.ACSL6: Acyl-CoA synthetase long-chain family member 6 is an enzyme that in humans is encoded by the ACSL6 gene. Long-chain acyl-CoA synthetases such as ACSL6, catalyze the formation of acyl-CoA from fatty acids, ATP, and CoA.Ubiquitin-conjugating enzymeF-box protein
