Protein

2-methylcitrate dehydratase

Gene

prpD

Organism
Escherichia coli (strain K12)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Catalyzes the dehydration of 2-methylcitrate to 2-methyl-cis-aconitate. Also seems to be responsible for the residual aconitase activity of the acnAB-null strain.

Catalytic activityi

(2S,3S)-2-hydroxybutane-1,2,3-tricarboxylate = (Z)-but-2-ene-1,2,3-tricarboxylate + H2O.1 Publication

Cofactori

[2Fe-2S] clusterNote: Binds 1 [2Fe-2S] cluster.
