چکیده

A soluble fructose-1,6-bisphosphate aldolase enzyme has been purified 50.2-fold (2.36%) at the homogeneity from the electric organ of Electrophorus electricus by one step of DEAE-52 anion exchange chromatography followed by Superose-12 gel filtration-FPLC. Like other aldolase enzymes the E. electricus protein is a dimer with two identical subunits of 45 kDa. The N-terminal (20 residues) revealed a high homology with S. aurata (75%, goldfish), R. ratus and M. musculus (mouse, 80%) enzymes.

Purification and partial characterization of glyceraldehyde-phosphate dehydrogenase from electric organ of Electrophorus electricus (L.).

The glyceraldehyde-phosphate dehydrogenase (GAPDH, EC 1.2.1.12) was purified to homogeneity from electric organ of Electrophorus electricus (L.) by a hydrophobic chromatography method on deacetylcolchicine-Sepharose. The purification resulted in a 162 fold increase in specific activity of the GAPDH and final yield was approximately 37%. The purified enzyme showed a single band in SDS-PAGE, with...

Characterization, kinetics, and crystal structures of fructose-1,6-bisphosphate aldolase from the human parasite, Giardia lamblia.

Class I and class II fructose-1,6-bisphosphate aldolases (FBPA), glycolytic pathway enzymes, exhibit no amino acid sequence homology and utilize two different catalytic mechanisms. The mammalian class I FBPA employs a Schiff base mechanism, whereas the human parasitic protozoan Giardia lamblia class II FBPA is a zinc-dependent enzyme. In this study, we have explored the potential exploitation o...

D-tagatose 1,6-diphosphate aldolase from lactic streptococci: purification, properties, and use in measuring intracellular tagatose 1,6-diphosphate.

Two D-ketohexose 1,6-diphosphate aldolases are present in Streptococcus cremoris E8 and S. lactis C10. One aldolase, which was induced by growth on either lactose or galactose, was active with both tagatose 1,6-diphosphate (TDP) and fructose 1,6-diphosphate (FDP), having a lower Km and a higher Vmax with TDP as the substrate. This enzyme, named TDP aldolase, had properties typical of a class I ...

Gestational diabetes mellitus is described as glucose intolerance at various degrees that is first detected during pregnancy. In diabetic complications, there are changes in placental function, particularly with respect to intake, transmit, and utilization of glucose, and also in glycolysis and glycolytic enzymes. The placenta possibly plays a critical role in protecting the fetus from adverse ...

Immunochemical studies using polyclonal antisera prepared individually against highly purified cytosolic and chloroplast spinach leaf (Spinacia oleracea) fructose bisphosphate aldolases showed significant cross reaction between both forms of spinach aldolase and their heterologous antisera. The individual cross reactions were estimated to be approximately 50% in both cases under conditions of a...
