Protein Family Models

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. [1]. 8909293.

Members of this family include fumarate hydratase, L-aspartate ammonia-lyase, argininosuccinate lyase, and adenylosuccinate lyase. All are classified as lyases, meaning these enzymes break a bond by an eliminating reaction that does not involve hydrolysis or oxidation.

Putative fumarases from several species (Mycobacterium tuberculosis, Streptomyces coelicolor, Pseudomonas aeruginosa) branch deeply, although within the same branch of a phylogenetic tree rooted by aspartate ammonia-lyase sequences, and score between the trusted and noise cutoffs.
