1. A malato desidrogenase solúvel de Hoplias malabaricus (Erythrinidae, Characiformes)
A fim de avaliar uma possível duplicação gênica recente no loco sMDH-A* de Hoplias malabaricus, foram analisadas as propriedades eletrocinéticas, cinéticas e de termoestabilidade da malato desidrogenase, estudando-se extratos brutos de fígado e de músculo esquelético, assim como de suas diferentes isoformas isoladas. O efeito do pH sobre a atividade

2. Duplicated cytosolic malate dehydrogenase genes in Zea mays
Six inbred lines of Zea mays expressing different soluble (cytosolic) malate dehydrogenase (sMDH) zymogram phenotypes were analyzed genetically. sMDH was found to be coded for by unlinked duplicated loci in four of these inbred lines. The remaining two lines were found not to possess these duplicated loci. Furthermore, the duplicated loci, sMdh1 and sMdh2, h

3. Purification and Properties of Cytoplasmic and Mitochondrial Malate Dehydrogenases of Physarum polycephalum
Two isoenzymes of malate dehydrogenase (MDH) were demonstrated in plasmodia of Physarum polycephalum by polyacrylamide-gel electrophoresis. The more “cathodal” form was uniquely associated with mitochondria (M-MDH) and the other form was found in the soluble cytoplasm (S-MDH). The isoenzymes were separated by acetone fractionation of soluble plasmodial h

4. 23S rRNA assisted folding of cytoplasmic malate dehydrogenase is distinctly different from its self-folding
The role of the 50S particle of Escherichia coli ribosome and its 23S rRNA in the refolding and subunit association of dimeric porcine heart cytoplasmic malate dehydrogenase (s-MDH) has been investigated. The self-reconstitution of s-MDH is governed by two parallel pathways representing the folding of the inactive monomeric and the dimeric intermediates. How

5. Amino acid sequence homology among the 2-hydroxy acid dehydrogenases: mitochondrial and cytoplasmic malate dehydrogenases form a homologous system with lactate dehydrogenase.
The amino acid sequence of porcine heart mitochondrial malate dehydrogenase (mMDH; L-malate: NAD+ oxidoreductase, EC 1.1.1.37) has been compared with the sequences of six different lactate dehydrogenases (LDH; L-lactate: NAD+ oxidoreductase, EC 1.1.1.27) and with the "x-ray" sequence of cytoplasmic malate dehydrogenase (sMDH). The main points are that (i) al
