Malate Dehydrogenases – Structure and Function
... MDHs, similar to LDHs, catalyze the conversion of 2-hydroxy acids to the corresponding 2-keto acids (Banaszak and Bradshaw 1975; Birktoft et al. 1982), but MDHs are specific for oxaloacetate and LDH for pyruvate substrate. It is known from kinetic studies that the malate to oxaloacetate reaction is ...

Protein structure prediction
Protein structure prediction is the prediction of the three-dimensional structure of a protein from its amino acid sequence — that is, the prediction of its folding and its secondary, tertiary, and quaternary structure from its primary structure. Structure prediction is fundamentally different from the inverse problem of protein design. Protein structure prediction is one of the most important goals pursued by bioinformatics and theoretical chemistry; it is highly important in medicine (for example, in drug design) and biotechnology (for example, in the design of novel enzymes). Every two years, the performance of current methods is assessed in the CASP experiment (Critical Assessment of Techniques for Protein Structure Prediction). A continuous evaluation of protein structure prediction web servers is performed by the community project CAMEO3D.
