<prompt> Rossman fold associated NADH domain is found in which of the following enzyme:Isocitrate DehydrogenasePyruvate DehydrogenaseCitrate synthaseSuccinate Dehydrogenase  <response>: Rossmann fold bab fold- a super-secondary structure Named after Michael Rossmann Characterized by an alternating bab beta strand-alpha helix-beta strand The bab fold structure is commonly observed in enzymes that have dinucleotide coenzymesFAD, SAM, NAD and NADP Found in a lot of dehydrogenase enzymes towards N-terminal end. It is also found in alcohol dehydrogenase enzyme The enzymes which have Rossmann fold are known as Rossmann enzymes e.g. Glyceraldehyde-3-Phosphate Dehydrogenase Alcohol Dehydrogenase Isocitrate Dehydrogenase Lactate Dehydrogenase Phosphoglycerate Dehydrogenase Glutathione Reductase D-AminoAcid Oxidase
