Aldolase A (ALDOA, or ALDA), also known as fructose-bisphosphate aldolase, is an enzyme that in humans is encoded by the ALDOA gene on chromosome 16.. The protein encoded by this gene is a glycolytic enzyme that catalyzes the reversible conversion of fructose-1,6-bisphosphate to glyceraldehyde 3-phosphate (G3P) and dihydroxyacetone phosphate (DHAP).
Fructose-bisphosphate aldolase (EC 4.1.2.13), often just aldolase, is an enzyme catalyzing a reversible reaction that splits the aldol, fructose 1,6-bisphosphate, into the triose phosphates dihydroxyacetone phosphate (DHAP) and glyceraldehyde 3-phosphate (G3P). Aldolase can also produce DHAP from other (3S,4R)- ketose 1-phosphates such as ...
Fructose-bisphosphate aldolase [EC 4.1.2.13] catalyzes a key reaction in glycolysis and energy production and is produced by all four species. [19] The P.falciparum aldolase is a 41 kDa protein and has 61-68% sequence similarity to known eukaryotic aldolases. [20] Its crystal structure has been published. [21]
HFI is caused by a deficiency of aldolase B. [5] A deficiency of aldolase B results in an accumulation of fructose-1-phosphate, and trapping of phosphate (fructokinase requires adenosine triphosphate (ATP)). The downstream effects of this enzyme block are the inhibition of glucose production and reduced regeneration of ATP. [5]
Aldolase A deficiency is an autosomal recessive [ 3 ] metabolic disorder resulting in a deficiency of the enzyme aldolase A; the enzyme is found predominantly in red blood cells and muscle tissue. The deficiency may lead to hemolytic anaemia as well as myopathy associated with exercise intolerance and rhabdomyolysis in some cases.
The enzyme deoxyribose-phosphate aldolase (EC 4.1.2.4) catalyzes the reversible chemical reaction. This enzyme belongs to the family of lyases, specifically the aldehyde-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is 2-deoxy-D-ribose-5-phosphate acetaldehyde-lyase (D-glyceraldehyde-3-phosphate-forming).
Carnitine biosynthesis is a method for the endogenous production of L-carnitine, a molecule that is essential for energy metabolism. [1][2][3][4] In humans and many other animals, L-carnitine is obtained from both diet and by biosynthesis. [5][6] The carnitine biosynthesis pathway is highly conserved among many eukaryotes and some prokaryotes ...
Fructokinase (/fruc•to•ki•nase/ [-ki´nas]), also known as D -fructokinase or D -fructose (D -mannose) kinase, [ 1 ] is an enzyme (EC 2.7.1.4) of the liver, intestine, and kidney cortex. Fructokinase is in a family of enzymes called transferases, meaning that this enzyme transfers functional groups; it is also considered a ...
