UniProtKB description: Contributes to the degradation of lignin at the level of the protocatechuate 4,5-cleavage pathway (PubMed:9864312). Catalyzes the hydrolysis of 2-pyrone-4,6-dicarboxylate (PDC) to (4E)-oxalomesaconate (OMA) (PubMed:22475079, PubMed:29658701). The keto form of OMA can tautomerize into the enol form, 4-carboxy-2-hydroxymuconate (CHM), under certain pH conditions (PubMed:22475079). Also catalyzes the reverse reaction (PubMed:22475079, PubMed:9864312). Is essential for the growth of Sphingobium sp. SYK-6 on vanillate but is not responsible for the growth of this strain on syringate (PubMed:9864312).
