WebThis is what causes an enzyme to have specificity for a substrate. Think about it logically. Different confirmations of various shaped and sized amino acid residues coming together would form various shapes/sizes of clefts or crevices (active site). Therefore, only certain sized and shaped substrates could fit and bind there. WebEnzyme specificity is defined as the ability of an enzyme to select an exact substrate from a group of the same chemical molecules converting it into its products.
