Water molecules play a number of critical roles in enzyme catalysis, including mass transfer of substrates and products, nucleophilicity and proton transfer at the active site, and solvent ...

Enzymes evolved to efficiently operate in low-temperature environments via key substitutions of amino acids in their active site, which lowers the activation energy of catalytic reactions. Life has ...

This investigation tests how well the enzyme amylase performs at different pH values. Amylase is a carbohydrase enzyme made by the pancreas and by glands in and around the mouth and throat. It helps ...
