  • subunit
  • Class I enzymes are heterodimers and exist in multiple isoforms consisting of one catalytic subunit (p110alpha, beta, gamma or delta) and one of several regulatory subunits (p85alpha, beta or gamma). (ebi.ac.uk)
  • DNA polymerase alpha catalytic subunit is an enzyme that in humans is encoded by the POLA1 gene. (wikipedia.org)
  • The Pol α complex (pol α-DNA primase complex) consists of four subunits: the catalytic subunit POLA1, the regulatory subunit POLA2, and the small and the large primase subunits PRIM1 and PRIM2 respectively. (wikipedia.org)
  • hydrocarbons
  • The overhead liquid distillate is called naphtha and will become a major component of the refinery's gasoline (petrol) product after it is further processed through a catalytic hydrodesulfurizer to remove sulfur-containing hydrocarbons and a catalytic reformer to reform its hydrocarbon molecules into more complex molecules with a higher octane rating value. (wikipedia.org)
  • It is the straight-run heavy naphtha that is usually processed in a catalytic reformer because the light naphtha has molecules with 6 or fewer carbon atoms which, when reformed, tend to crack into butane and lower molecular weight hydrocarbons which are not useful as high-octane gasoline blending components. (wikipedia.org)
  • Cracking of petroleum hydrocarbons was originally done by thermal cracking, which has been almost completely replaced by catalytic cracking because it produces more gasoline with a higher octane rating. (wikipedia.org)
  • gases
  • A process for catalytically cracking a hydrocarbon-containing feed stream, preferably having an API60 gravity of about 5-30, wherein at least a portion of off-gases is treated so as to remove C2 -C4 olefins therefrom, and the off-gas stream having a reduced olefin content is then recycled to the catalytic.

  • Parts Train is your complete online source for everything Chevrolet, and to prevent your Chevy from emitting harmful gases, we offer you nothing but the best Chevy catalytic converters. (partstrain.com)
  • hydrogen
  • This process is quite different from and not to be confused with the catalytic steam reforming process used industrially to produce products such as hydrogen, ammonia, and methanol from natural gas, naphtha or other petroleum-derived feedstocks. (wikipedia.org)
  • Mechanistically, catalytic chain transfer involves hydrogen atom transfer from the organic growing polymeryl radical to cobalt(II), thus leaving a polymer vinyl-end group and a cobalt-hydride species. (wikipedia.org)
  • Exhaust

  • Judging by its function, the catalytic converter seems to be just a simple device that filters out harmful substances from your vehicle engine's exhaust. (partstrain.com)
  • To prevent these substances from getting out of the vehicle's exhaust system and harm the environment, auto manufacturers like Chevrolet uses catalytic converters. (partstrain.com)
  • Although catalytic converters are most commonly applied to exhaust systems in automobiles, they are also used on electrical generators, forklifts, mining equipment, trucks, buses, locomotives and motorcycles. (wikipedia.org)
  • process
  • But the process that goes inside the catalytic converter is not simply a filtering process but something more complex. (partstrain.com)
  • The process that goes inside the catalytic converter is easy to understand, but the design of such converters are more complex than what most of us think of. (partstrain.com)
  • Nonetheless, Chevrolet has been able to master the design and manufacturing process of their Chevrolet catalytic converters. (partstrain.com)
  • Articles on the Monsanto process, the Wacker process, and the Heck reaction show catalytic cycles. (wikipedia.org)
  • Catalytic reforming is a chemical process used to convert petroleum refinery naphthas distilled from crude oil (typically having low octane ratings) into high-octane liquid products called reformates, which are premium blending stocks for high-octane gasoline. (wikipedia.org)
  • Today, the large majority of gasoline produced worldwide is derived from the catalytic reforming process. (wikipedia.org)
  • The fractal catalytic model (also referred to as the fractal catalytic theory or soliton-catalytic model) - proposed by Christopher James Davia and adopted in the research of Carnegie Mellon University (Lee and Marge Gregg) Professor of Psychology Patricia Carpenter - is a "theory of cognition grounded in metabolism" which identifies enzymatic catalysis (taking place in cells) as a "prototypical process" applying at all levels of scale in biological organisms. (wikipedia.org)
  • Catalytic chain transfer (CCT) is a process that can be incorporated into radical polymerization to obtain greater control over the resulting products. (wikipedia.org)
  • One of the major drawbacks of the process is that catalytic chain transfer polymerization does not produce macromonomers of use in free radical polymerizations, but instead produces addition-fragmentation agents. (wikipedia.org)
  • The catalytic chain transfer process was commercialized very soon after its discovery. (wikipedia.org)
  • residue
  • Each of the lobes provides a catalytic Asp residue, positioned within the hallmark motif Asp-Thr/Ser-Gly, to the active site. (ebi.ac.uk)
  • Catalytic triads perform covalent catalysis using a residue as a nucleophile. (wikipedia.org)
  • reactive

  • Studies have shown that synthetic catalytic scavengers have superoxide dismutase and catalase activities which prevented injuries from reactive oxygen species. (wikipedia.org)
  • 2002
  • The cordierite ceramic substrate used in most catalytic converters was invented by Rodney Bagley, Irwin Lachman and Ronald Lewis at Corning Glass, for which they were inducted into the National Inventors Hall of Fame in 2002. (wikipedia.org)
  • entry represents
  • This entry represents the catalytic domain of PI3Kalpha (also known as p110alpha), which is a Class IA phosphoinositide-3-kinase (PI3K) that that phosphorylates PtdIns (Phosphatidylinositol), PtdIns4P (Phosphatidylinositol 4-phosphate) and PtdIns(4,5)P2 (Phosphatidylinositol 4,5-bisphosphate) to generate phosphatidylinositol 3,4,5-trisphosphate (PIP3). (ebi.ac.uk)
  • substrate
  • Enzymes that contain a catalytic triad use it for one of two reaction types: either to split a substrate (hydrolases) or to transfer one portion of a substrate over to a second substrate (transferases). (wikipedia.org)
  • consists
  • The catalytic bead sensor consists of two coils of fine platinum wire each embedded in a bead of alumina, connected electrically in a Wheatstone bridge circuit. (wikipedia.org)
