Enzyme Information
| 4.2.1.99 |
2-methylisocitrate dehydratase.
based on mapping to UniProt P36683
(2S,3R)-3-hydroxybutane-1,2,3-tricarboxylate = (Z)-but-2-ene-1,2,3- tricarboxylate + H(2)O.
-!- The enzyme from the fungus Yarrowia lipolytica does not act on isocitrate.
|
| 4.2.1.3 |
Aconitate hydratase.
based on mapping to UniProt P36683
Citrate = isocitrate.
-!- Besides interconverting citrate and cis-aconitate, it also interconverts cis-aconitate with isocitrate and, hence, interconverts citrate and isocitrate. -!- The equilibrium mixture is 91% citrate, 6% isocitrate and 3% aconitate. -!- Cis-aconitate is used to designate the isomer (Z)-prop-1-ene-1,2,3- tricarboxylate. -!- Formerly EC 4.2.1.4.
