The following reaction depicts the activity of a particular class of enzymes : [figure] Identify the enzyme class 'E' from the following options :
- Isomerases
- Ligases
- Transferases
- Lyases

(4) Lyases
Solution
The groups X and Y are removed from the substrate without hydrolysis, and a double bond (C = C) is left behind.
Enzymes that catalyse removal of groups from substrates by mechanisms other than hydrolysis, forming double bonds, are lyases.
