Part A - Overview of enzyme structure and enzymatic reactions Enzymes are large globular proteins. Much of their three dimensional shape is the result of interactions between the R (variable) groups of their amino acids. The active site is the portion of the enzyme that will interact with the substrate the molecule that the enzyme acts upon. The nature and arrangement of amino acids in the active site make each enzyme specific to a substrate and to the reaction it...
