| Comment |
This enzyme participates in the degradation of 3,4-dihydroxybenzoate (via the meta-cleavage pathway), syringate and 3,4,5-trihydroxybenzoate, catalysing the reaction in the opposite direction [1-3]. It accepts the enol-form of 4-oxalomesaconate, 2-hydroxy-4-carboxy-hexa-2,4-dienedioate [4].
