metabolism
2-methylcitrate dehydratase and 1, 2-methylcitrate synthase are involved in energy metabolism and participate in the methylcitrate cycle, which is an important source of energy in the cell
metabolism
the enzyme is involved in the 2-methylcitric acid cycle, overview
metabolism
the enzyme is involved in the 2-methylcitric acid cycle, overview. The three genes, mmgDE and yqiQ (mmgF), provide three of the five steps of the methylcitric acid cycle, encoded in the mmg operon. The fourth step can be supplied by citB (aconitase), and the fifth probably missing step, the propionyl-CoA synthetase, is probably skipped because the beta-oxidation of methyl-branched fatty acids by the enzymes encoded by mmgABC produce propionyl-CoA. The 2-methylisocitrate produced by CitB is converted to pyruvate and succinate by the enzyme YqiQ(MmgF)

construction of enzyme-deficient DELTA prpD mutant. The two genes acnD and prpF, encoding 2-methylcitrate dehydratase (AcnD, EC 4.2.1.117) and 2-methyl-aconitate isomerase (SoPrpF, EC 5.3.3.-) from Shewanella oneidensis together can replace gene prpD in Salmonella enterica. SoAcnD and SePrpD synthesize different methylaconitate isomers. The SoPrpF protein isomerizes the product of the AcnD reaction into the PrpD product. Mutant SoPrpF variants with substitutions of residues K73 or C107 fail to support growth with propionate as the sole source of carbon and energy

ipon silver stess 2-methylcitrate dehydratase and 2-methylcitrate synthase are strongly overexpressed
physiological function
the MmgE enzyme is not a stereospecific 2-methylcitrate dehydratase because it can dehydrate at least two of the four diastereomers of 2-methylcitrate to yield either (E)-2-methylaconitate or (Z)-2-methylaconitate, but the physiological pathways proceed via (Z)-2-methylaconitate, which serves as the substrate for the citB enzyme in the synthesis of 2-methylisocitrate
physiological function
the PrpD enzyme from Escherichia coli is not a stereospecific 2-methylcitrate dehydratase because it can dehydrate at least two of the four diastereomers of 2-methylcitrate to yield either (E)-2-methylaconitate or (Z)-2-methylaconitate, but the physiological pathways proceed via (Z)-2-methylaconitate, which serves as the substrate for the citB enzyme in the synthesis of 2-methylisocitrate
