General annotation (Comments)

Function

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 activity

(2S,3S)-2-hydroxybutane-1,2,3-tricarboxylate = (Z)-but-2-ene-1,2,3-tricarboxylate + H2O. Ref.5

Cofactor

Binds 1 2Fe-2S cluster.

Pathway

Organic acid metabolism; propanoate degradation.

Subunit structure

Monomer.

Sequence similarities

Belongs to the PrpD family.

Biophysicochemical properties

Kinetic parameters:

KM=0.44 mM for (2S,3S)-2-methylcitrate Ref.5
