Disulfides (glutathione disulfide, cystine, cystamine) caused a first-order inactivation of rabbit-muscle fructose-1,6-bisphosphate aldolase at pH values of 7.4 and above. Inactivation by glutathione disulfide was partially reversed by reducing agents, but the enzyme became irreversibly inactivated with time. The disulfide-inactivated aldolase had a lower transition temperature and enthalpy of ...

Centromeric to C9orf125 (chromosome 9 open reading frame 125), RNF20 (ring finger protein 20), PP...

Fructose-1,6-bisphosphate aldolase A (fructose-bisphosphate aldolase; EC 4.1.2.13) deficiency is an autosomal recessive disorder associated with hereditary hemolytic anemia. To clarify the molecular mechanism of the deficiency at the nucleotide level, we have cloned aldolase A cDNA from a patient's poly(A)+ RNA that was expressed in cultured lymphoblastoid cells. Nucleotide analysis of the pati...

A single fructose1,6-bisphosphate (FBP) aldolase has been detected in extracts from carrot storage roots (Daucus carota L.). The enzyme was purified 850-fold to electrophoretic homogeneity and a final specific activity of 26.3 amol of FBP utilized/min per mg of protein. SDS/PAGE of the final preparation revealed a single protein-staining band of 40 kDa. The native molecular mass was determined ...

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...

Fructose-1,6-bisphosphate aldolase from Drosophila melanogaster has been crystallized from polyethylene glycol 6000 by vapor diffusion technique against buffered polyethylene glycol solutions at 2-4 degrees C. The insect enzyme crystallizes in the orthorhombic system, heretofore unknown for aldolases. The crystals have the space group P212121 (a = 86.3 A, b = 115.7 A, and c = 151.4 A) and conta...

The glycolytic enzymes of Trypanosomatids are compartmentalized within peroxisome-like microbodies called glycosomes. Fructose bisphosphate aldolase is synthesized on free polysomes and imported into glycosomes within 5 min. Peptide mapping reveals no primary structural differences between the in vivo-synthesized protein and that made in vitro from a synthetic template. However, native aldolase...

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) reveale...
