(1) The kinetic data are compatible with a tert-uni ping-pong mechanism, as in the case of the 'classical' glutathione peroxidase (EC 1.11.1.9).
(2) Initial-velocity kinetic studies indicate the enzyme acts by a ping-pong mechanism.
(3) Initial velocity and isotope exchange studies confirmed that the over-all reaction, like that catalyzed by pyruvate carboxylase purified from rat liver and chicken liver, was a nonclassical Ping Pong Bi Bi Uni Uni sequence with ATP and HCO3-binding randomly in the Bi Bi partial reaction.
(4) The asymptotic kinetics of lipoamide oxidoreductions switch between the ping pong and ordered mechanisms by varying pH of the reactions.
(5) Penetration of these drugs into perforated ping pong balls implanted intraperitoneally in rabbits was studied.
(6) The results obtained were consistent with a ping-pong or substitution mechanism.
(7) Since each catalytic cycle step is irreversible, the data fit a peroxidase ping-pong mechanism rather than an ordered bi-bi ping-pong mechanism.
(8) And then, proving that in the celebrity world of self-abasement there really is no such thing as "bottoming out", Shane started tweeting Ping Pong, otherwise known as Elizabeth Hurley's parrot Why has Australia not staged an intervention?
(9) It seems most probable that, as previously suggested by others for Ts, eIF-2B effectively catalyses an exchange reaction through a "ping-pong" type mechanism.
(10) Initial velocity studies indicate that the enzymatic reaction proceeds by a Ping-Pong mechanism.
(11) This reaction pathway is compared with the double displacement (Ping Pong) mechanisms that have previously been described for pyruvate carboxylases from other sources.
(12) The wild-type enzyme and Y177F mutant displayed ping-pong kinetics, but the Y177S and Y177G mutants appeared to have switched to an ordered sequential mechanism.
(13) But I don’t think [Lords chief whip] Ben Stoneham is going to be very accommodating to anyone.” Brexit weekly briefing: article 50 moves closer but EU dashes divorce deal hopes Read more Labour has promised no “extended ping pong” as it does not want to frustrate the timetable for triggering article 50, but it has laid eight amendments on issues from EU nationals to quarterly reporting to parliament about the Brexit process.
(14) Initial velocity measurements in which the concentration of L-alpha-methyl-gamma-glutamyl-L-alpha-aminobutyrate was varied at several fixed acceptor concentrations, and either the release of alpha-aminobutyrate or the formation of the transpeptidation products was determined, yielded results which are consistent with a ping-pong mechanism modified by a hydrolytic shunt.
(15) Contrary to findings with another enzyme (fraction I), a Bi Uni Uni Bi Ping Pong mechanism (Cleland, 1963a,b,c) corresponding to Berg's (1956) scheme of reaction was eliminated and an ordered Ter Ter mechanism with an A-C-B (standing for ATP, CoA and butyrate respectively) sequence of substrate entry for the overall reaction was established for fraction II.
(16) The Peak Ia and Peak II enzymes both absolutely require alpha-D-glucose 1,6-bisphosphate and Mg2+ for activity, and appear to have a "ping-pong" mechanism.
(17) Neuronal as well as astrocytic GABA-transaminase obeyed a bi bi ping-pong reaction mechanism.
(18) The N-acetylglucosamine and mannitol enzymes II, which do not function with an enzyme III, catalyze sugar phosphorylation by a ping-pong mechanism when the two substrates are phospho-HPr and sugar.
(19) Constant-ratio double-reciprocal plots confirm that the enzyme mechanism is nonsequential (ping-pong bi-bi).
(20) In contrast, a comparable reaction of the A-U-G analog with 30S subunits lead to a predominant crosslinking of A-U-G to proteins S4 and S12 (Pongs, O., Stoffler, G.A., Lanka, E., (1975) J. Mol.
