Alteration of substrate specificity by a naturally-occurring aldolase B mutation (Ala337-->Val) in fructose intolerance.
A molecular analysis of human aldolase B genes in two newborn infants and a 4-year-old child with hereditary fructose intolerance, the offspring of a consanguineous union, has identified the novel mutation Ala337-->Val in homozygous form. This mutation was also detected independently in two other affected individuals who were compound heterozygotes for the prevalent aldolase B allele, Ala149-->...
متن کاملThe carboxyl-terminal structure of rabbit liver aldolase (aldolase B).
The amino acid residues in the carboxyl-terminal region of fructose diphosphate aldolase isolated from fresh rabbit liver are -(Gly,Phe,Leu,Ala,Thr2,Ser2)-Tyr. This differs from the carboxyl-terminal structure in aldolase isolated from tissue which had been frozen and thawed. Amino acid analyses, ultracentrifugation, and digestion with carboxypeptidase suggest that the difference is the result ...
متن کاملStructural insights into the substrate binding and stereoselectivity of giardia fructose-1,6-bisphosphate aldolase.
Giardia lamblia fructose-1,6-bisphosphate aldolase (FBPA) is a member of the class II zinc-dependent aldolase family that catalyzes the cleavage of d-fructose 1,6-bisphosphate (FBP) into dihydroxyacetone phosphate (DHAP) and d-glyceraldehyde 3-phosphate (G3P). In addition to the active site zinc, the catalytic apparatus of FBPA employs an aspartic acid, Asp83 in the G. lamblia enzyme, which whe...

متن کاملReversible microsomal binding of hepatic aldolase.
Fructose-1,6-bisphosphate aldolase (D-fructose-1,6-bisphosphate D-glyceraldehyde-3-phosphate lyase, EC 4.1.2.13) partitions between the microsomes and the cytosol when a rat liver homogenate is fractionated by differential centrifugation. Gel electrophoresis and immunodiffusion indicate that the one isozyme present in the liver of the young adult rat is found in both fractions. The association ...
