This entry represents the N-terminal domain of 2-methylcitrate dehydratase EC:4.2.1.79 (PrpD) that is required for propionate catabolism. It catalyses the third step of the 2-methylcitric acid cycle [1]. This enzyme consists of two domains: a large domain with an all-helical fold and a smaller domain that folds into an alpha/beta domain [2]. Cis-aconitic acid decarboxylase (CAD) shares high identity with proteins of the MmgE/PrpD family [3,4]. Citrate/2-methylcitrate dehydratase from Bacillus subtilis is involved in the tricarboxylic acid (TCA) and methylcitric acid cycles as it has both 2-methylcitrate dehydratase and citrate dehydratase activities [5]. This entry represents the N-terminal domain of 2-methylcitrate dehydratase PrpD, which has an all-helical fold.	Domain
