3-dehydroshikimate dehydratase

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

3-dehydro-shikimate

\rightleftharpoons

3,4-dihydroxybenzoate + H₂O

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