Thanks to these amino acids, an enzymes active site is uniquely suited to bind to a particular targetthe enzymes substrate or substratesand help them undergo a chemical reaction. the spacial positioning or pairing of complementary positive and negative charges helps to establish charge-charge interactions, stabilizing effect. At last, glucose and fructose are released as products form the sucrase enzyme. That is, active site residues may form temporary covalent bonds with substrate molecules as part of the reaction process. The active site refers to the specific region of an enzyme where a substrate binds and catalysis takes place or where chemical reaction occurs. They may be involved in catalysis and substrate binding, stabilize the intermediates of the reaction or the structure of the binding cleft.
