What are the different types of enzyme specificity with examples?
Enzymes exhibit different types of specificity, including substrate specificity (acting on a specific substrate), stereospecificity (acting on a specific stereoisomer), and regiospecificity (acting at a specific region of a substrate). For example, trypsin exhibits substrate specificity by cleaving peptide bonds after lysine or arginine residues, while lactase exhibits substrate specificity by hydrolyzing lactose.
