STRUCTURAL FEATURES STABILIZING HALOPHILIC MALATE DEHYDROGENASE FROM AN ARCHAEBACTERIUMSTRUCTURAL FEATURES STABILIZING HALOPHILIC MALATE DEHYDROGENASE FROM AN ARCHAEBACTERIUM
Structural highlights
Function[MDH_HALMA] Catalyzes the reversible oxidation of malate to oxaloacetate.[HAMAP-Rule:MF_00487] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe high-resolution structure of halophilic malate dehydrogenase (hMDH) from the archaebacterium Haloarcula marismortui was determined by x-ray crystallography. Comparison of the three-dimensional structures of hMDH and its nonhalophilic congeners reveals structural features that may promote the stability of hMDH at high salt concentrations. These features include an excess of acidic over basic residues distributed on the enzyme surface and more salt bridges present in hMDH compared with its nonhalophilic counterparts. Other features that contribute to the stabilization of thermophilic lactate dehydrogenase and thermophilic MDH-the incorporation of alanine into alpha helices and the introduction of negatively charged amino acids near their amino termini, both of which stabilize the alpha helix as a result of interaction with the positive part of the alpha-helix dipole-also were observed in hMDH.
