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

Options

  1. AHydrolase
  2. BLyase
  3. CTransferase
  4. DLigase

Correct answer

C. Transferase

Step-by-step solution

Enzymes catalysing a transfer of GG group, (other than hydrogen) between a pair of substrates, S and S′\mathrm{S}^{\prime} are known as transferases. S−G+S#→ S+S#−G\mathrm{S}-\mathrm{G}+\mathrm{S}^{\#} \rightarrow \mathrm{~S}+\mathrm{S}^{\#}-\mathrm{G} - Ligases catalyse the linking together of 2 compounds such as C−O,C−S,C−NC-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, C−C,C\mathrm{C}-\mathrm{C}, \mathrm{C} - halide or P−N\mathrm{P}-\mathrm{N} bonds.
