[https://www.uniprot.org/uniprot/HACB_METJA HACB_METJA] Hydro-lyase with broad substrate specificity for cis-unsaturated tricarboxylic acids. Catalyzes both the reversible dehydration of (R)-homocitrate ((R)-2-hydroxybutane-1,2,4-tricarboxylate) to produce cis-homoaconitate ((Z)-but-1-ene-1,2,4-tricarboxylate), and its hydration to homoisocitrate ((1R,2S)-1-hydroxybutane-1,2,4-tricarboxylate). Is also able to hydrate the analogous longer chain substrates cis-homo(2)-aconitate, cis-homo(3)-aconitate, and even the non-physiological cis-homo(4)-aconitate with similar efficiency. These reactions are part of the biosynthesis pathway of coenzyme B. Can also catalyze the hydration of maleate to (R)-malate, and that of cis-aconitate. Can not catalyze the hydration of citraconate and the dehydration of (S)-homocitrate, citramalate, 2-isopropylmalate, 3-isopropylmalate, citrate or threo-DL-isocitrate.<ref>PMID:17449626</ref> <ref>PMID:18765671</ref> <ref>PMID:20170198</ref>
