Accepted name: 2-methylcitrate dehydratase
Reaction: (2S,3S)-2-hydroxybutane-1,2,3-tricarboxylate = (Z)-but-2-ene-1,2,3-tricarboxylate + H2O
Glossary: (2S,3S)-2-methylcitrate = (2S,3S)-2-hydroxybutane-1,2,3-tricarboxylate
cis-2-methylaconitate = (Z)-but-2-ene-1,2,3-tricarboxylate
Other name(s): 2-methylcitrate hydro-lyase; PrpD; 2-hydroxybutane-1,2,3-tricarboxylate hydro-lyase
Systematic name: (2S,3S)-2-hydroxybutane-1,2,3-tricarboxylate hydro-lyase [(Z)-but-2-ene-1,2,3-tricarboxylate-forming]
Comments: The enzyme is specific for (2S,3S)-methylcitrate, showing no activity with (2R,3S)-methylcitrate [2]. The enzyme can also use cis-aconitate as a substrate but more slowly [2]. Both this enzyme and EC, aconitate hydratase, are required to complete the isomerization of (2S,3S)-methylcitrate to (2R,3S)-2-methylisocitrate [2].
