== Publication Abstract from PubMed ==
 +
rv1098c, an essential gene in Mycobacterium tuberculosis, codes for a class II fumarase. We describe here the crystal structure of Rv1098c in complex with l-malate, fumarate or the competitive inhibitor meso-tartrate. The models reveal that substrate binding promotes the closure of the active site through conformational changes involving the catalytic SS-loop and the C-terminal domain, which likely represents a general feature of this enzyme superfamily. Analysis of ligand-enzyme interactions as well as site-directed mutagenesis suggest Ser318 as one of the two acid-base catalysts. STRUCTURED SUMMARY OF PROTEIN INTERACTIONS: Rv1098c and Rv1098c bind by X-ray crystallography (View interaction).
