Name the class of enzyme that usually catalyze the following reaction :
\(\mathrm{S}-\mathrm{G}+\mathrm{S}^{\prime} \rightarrow \mathrm{~S}+\mathrm{S}^{\prime}-\mathrm{G}\)
Where, \(G \rightarrow\) a group other than hydrogen
\(S \rightarrow\) a substrate
\(\mathrm{S}^{\prime} \rightarrow\) another substrate

Enzymes catalysing a transfer of \(G\) group, (other than hydrogen) between a pair of substrates, S and \(\mathrm{S}^{\prime}\) are known as transferases.
\(\mathrm{S}-\mathrm{G}+\mathrm{S}^{\prime} \rightarrow \mathrm{~S}+\mathrm{S}^{\prime}-\mathrm{G}\)
- Ligases catalyse the linking together of 2 compounds such as \(C-O, C-S, C-N\) bonds etc
- Lyases catalyse removal of groups from substrates by mechanisms other than hydrolysis leaving double bonds
Hydrolases are enzymes that catalyse hydrolysis of ester, ether, peptide, glycosidic, \(\mathrm{C}-\mathrm{C}, \mathrm{C}\) - halide or \(\mathrm{P}-\mathrm{N}\) bonds.
