Fumarase C catalyses the stereo-specific interconversion of fumarate to L-malate as part of the Kreb's cycle. The full-length protein forms a tetramer with visible globular shape. FumaraseC_C is the C-terminal 65 residues referred to as domain 3. The core of the molecule consists of a bundle of 20 alpha-helices from the five-helix bundle of domain 2. The projections from the core of the tetramer are generated from domains 1 and 3 of each subunit [1]. FumaraseC_C does not appear to be part of either the active site or the activation site but is helical in structure forming a little bundle.	Domain

Chains	Enzyme Name	Description	Catalytic Residues
A, B	fumarate hydratase (class II) M-CSA #569	Fumarase catalyses the reversible stereospecific hydration/dehydration of fumarate to L-malate during Kreb's cycle. Fumarase C is a member of the class II enzymes, a family which also includes aspartase, adenylosuccinate lyase and arginosuccinate, with high sequence similarity among its members. Fumarse C differs from the class I fumarase A and B enzymes in its lack of an apparent iron sulphur cluster.
