3-dehydroshikimate dehydratase

3-dehydroshikimate dehydratase (EC 4.2.1.118) is an enzyme with systematic name 3-dehydroshikimate hydro-lyase.^[1]^[2] This enzyme catalyses the following chemical reaction

3-dehydro-shikimate

\rightleftharpoons

protocatechuate + H₂O

This enzyme catalyses an early step in the biosynthesis of petrobactin.
