What class of enzymes cleaves most aromatic rings in biological systems?

Question

Quizplus · Accepted Answer

Dioxygenases are a class of enzymes that use molecular oxygen to cleave aromatic rings in biological systems. They can either introduce two atoms of oxygen into the ring, or they can create an arene oxide intermediate that can be further transformed. Monooxygenases, biopterin-linked lyases, and aromatic oxidases also play important roles in the metabolism of aromatic compounds, but they do not cleave aromatic rings as frequently as dioxygenases do.
