– Bonds are broken/formed at the catalytic site. catalytic site of enzyme
The primary job of the catalytic site is to lower the ( Eacap E sub a While often grouped together, there is a distinction:
One of the most well-studied examples of a catalytic site is the found in chymotrypsin and other proteases. A temporary covalent bond forms between the substrate
Amino acid side chains can act as proton donors (acids) or proton acceptors (bases).
A temporary covalent bond forms between the substrate and a catalytic residue (often or Cysteine ). This creates a highly reactive intermediate that breaks down quickly into the final product. 3. Metal Ion Catalysis Many enzymes use metal ions (like Mg2+cap M g raised to the 2 plus power Zn2+cap Z n raised to the 2 plus power Fe2+cap F e raised to the 2 plus power
