Two-substrate reaction model for the heparin-catalyzed bovine antithrombin/protease reaction.

The kinetics of the heparin-dependent antithrombin/protease reaction were consistent with an ordered sequential two-substrate reaction model under all circumstances tested. In this model, heparin is the catalyst; while antithrombin is the first substrate and the protease is the second substrate. The first step in this reaction, the heparin-antithrombin interaction, has a KD of 25 nM but a diffu...

The Catalyzed Hydrosilation Reaction

Ab initio electronic structure calculations with RHF, MP2, and CCSD(T) wave functions have been used to investigate a reaction path for the hydrosilation reaction catalyzed by divalent titanium (modeled by TiH2). Optimized structures and energies are presented. All levels of theory predict a barrierless reaction path compared to a barrier of 78 kcal/mol for the uncatalyzed reaction. The use of ...

The Rhizopus niveus glucoamylase-catalyzed reaction for substrate maltose in the absence or presence of acetonitrile

In the presence or absence of acetonitrile CH3CN, the molecular mechanism on the Rhizopus niveus glucoamylse (GA)-catalyzed reaction was studied by the steady-state kinetics for a substrate maltose (G2). At high concentration of G2, the GA-catalyzed reaction was observed not to obey the Michaelis kinetics and was reasonably explained with a mechanism of the substrate-inhibition involving the te...

Palladium-Catalyzed, Enantioselective Heine Reaction

Aziridines are important synthetic intermediates for the generation of nitrogen-containing molecules. N-Acylaziridines undergo rearrangement by ring expansion to produce oxazolines, a process known as the Heine reaction. The first catalytic, enantioselective Heine reaction is reported for meso-N-acylaziridines where a palladium(II)-diphosphine complex is employed. The highly enantioenriched oxa...

Dehydroquinate synthase: the use of substrate analogues to probe the early steps of the catalyzed reaction.

The early steps of the proposed mechanistic pathway for dehydroquinate synthase have been probed with a series of substrate analogues. These analogues, 3-9, are structurally prohibited from undergoing the beta-elimination of inorganic phosphate that represents the committed step in the conversion of the substrate 3-deoxy-D-arabino-heptulosonate 7-phosphate (1) to dehydroquinate (2). In agreemen...
