Both scale up reactions delivered the target amides without affecting the overall yields. With additional process development, we envisage these reactions could be scaled up further, for future biomanufacturing. Finally, the potential for biocatalyst recycling was demonstrated by repeating the synthesis of...
We tested how well models that use enzyme information alone can predict turnover numbers. We trained a gradient boosting model34that used either the ESM-1b or ESM-1bESPvectors to predict thekcatvalue of enzyme-catalyzed reactions, without using any additional information on the reaction or on ...
A catalyst is a substance that accelerates a chemical reaction without changing the nature or quantity of products formed and without itself being consumed in the process. Enzymes are biological catalysts, i.e., they catalyze reactions in animal and plant tissue that, if performed in vitro , wou...
An enzyme, or ferment, is a definite chemical substance of organic nature, thermolabile and elaborated by plants, animals and microorganisms, and capable of increasing the velocity of a chemical reaction without being used up in the process, or becoming a part of the product formed. Many ...

However, it would take several hours to approach this equilibrium without enzyme, whereas equilibrium would be attained within a second when enzyme is present. Thus, enzymes accelerate the attainment of equilibria but do not shift their positions. Enzymes Decrease the Activation Energies of Reactions ...

All the other reagents were purchased from Sinopharm Chemical Reagent, Co. Ltd. and used without further purification. Ultrapure water (≥18.2 MΩ cm) was used throughout the study. Characterizations TEM images were obtained on JEOL JEM2010 operated at 200 kV. TGA was conducted on a ...
