S-Adenosyl-L-ethionine is S-Adenosyl-L-methione analog. S-Adenosyl-L-ethionine is able to replace S-Adenosyl-L-methione during HydG catalysis. HydG can utilize S-Adenosyl-L-ethionine as an effective alternative cosubstrate to S-Adenosyl-L-methione under normal enzymatic turnover conditions, producing the Ω intermediate and allowing efficient catalytic turnover of substrate L-tyrosine [1].
