Sentence examples for substrates in catalysis from inspiring English sources

The difference in energy between the two substrates in catalysis by the wild-type enzyme is +1.9 kcal indicating that a higher energy route is required to reach the transition state for 26,27-dehydrozymosterol 26,27-dehydrozymosterolth the topography of these interacatalysis

To the best of our knowledge, the transformations in Schemes 1, 3, and 5 (reactions i, iii vi) are the first to use ortho-silyl (hetero aryl triflates as substrates in catalysis not involving activation of the aryne or mediation of its reactivity by a transition metal.[ 11, 37] This points to broad new possibilities for incorporating aryne precursors into more complex chemical environments.

The reported 3D structure of the E. coli TPS enzyme allowed the identification of the amino acid residues involved in the binding of substrates and in catalysis [ 35].

Indeed, while the K187A mutant shows a slight reduction of the catalytic activity for PLP formation (Table 1B), it has a similar increase in KM for binding G3P compared to the other Pdx1 P2 muteins suggesting that this residue is more involved in binding the triose phosphate substrate than in catalysis.

Key residues involved in substrate binding or in catalysis were identified.

One unit (U) of hydantoinase activity is defined as the amount of enzyme that converts 1 µmol substrate per minute in catalysis buffer at 40 °C.

At this point every collision of the enzyme with its substrate will result in catalysis, and the rate of product formation is not limited by the reaction rate but by the diffusion rate.

Mutagenesis studies revealed that an active site arginine played a key role in binding the substrate donor and in catalysis, and an asparagine residue was important for binding to fucose and possibly positioning the nucleophilic water during catalysis.

This approach enables the unprecedented postfunctionalization of fluoride-activated (hetero aryne precursors, for example, as substrates in transition-metal catalysis, and offers valuable new possibilities for aryl boronate postfunctionalization without the use of specialized protecting groups.

By adding 500 μL of the particular substrate solution (10 mM in catalysis buffer), the reaction was started.

750 μL from this cell suspension were added to 750 μL of substrate solution (4 mM in catalysis buffer) to start the biotransformation reaction.
