Question:medium

Name the class of enzyme that usually catalyzes the following reaction: \[ S - G + S^{\prime} \rightarrow S + S^{\prime} - G \] Where \( G \) represents a group other than hydrogen, \( S \) is a substrate, and \( S^{\prime} \) is another substrate.

Show Hint

Lyases are enzymes that catalyze the addition or removal of groups to or from substrates without using water. Understanding the different types of enzymes helps to classify reactions correctly.

  • Lyase
  • Transferase
  • Ligase
  • Hydrolase
Hide Solution

The Correct Option is A

Solution and Explanation

The reaction in question entails bond formation or cleavage in substrates, typically mediated by lyases. Lyases are enzymes that catalyze the addition or elimination of functional groups from substrates, distinct from hydrolases which utilize water. Therefore, the appropriate enzyme class for this reaction is Lyase.
