                4.2.1.79 2-methylcitrate dehydratase
IUBMB Comments
The enzyme is specific for (2S,3S)-methylcitrate, showing no activity with (2R,3S)-methylcitrate . The enzyme can also use cis-aconitate as a substrate but more slowly . Both this enzyme and EC 4.2.1.3, aconitate hydratase, are required to complete the isomerization of (2S,3S)-methylcitrate to (2R,3S)-2-methylisocitrate .

(2S,3S)-2-hydroxybutane-1,2,3-tricarboxylate hydro-lyase [(Z)-but-2-ene-1,2,3-tricarboxylate-forming]
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 4.2.1.3, aconitate hydratase, are required to complete the isomerization of (2S,3S)-methylcitrate to (2R,3S)-2-methylisocitrate [2].
