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 ...
Endocrinology. 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.
Fructose 1,6-bisphosphate aldolase is another temperature dependent enzyme that plays an important role in the regulation of glycolysis and gluconeogenesis during hibernation. [14] Its main role is in glycolysis instead of gluconeogenesis, but its substrate is the same as FBPase's, so its activity affects that of FBPase in gluconeogenesis.
NCBI. proteins. In enzymology, aldose reductase (or aldehyde reductase) (EC 1.1.1.21) is an enzyme in humans encoded by the gene AKR1B1. It is an cytosolic NADPH -dependent oxidoreductase that catalyzes the reduction of a variety of aldehydes and carbonyls, including monosaccharides, and primarily known for catalyzing the reduction of glucose ...
Acetaldehyde dehydrogenases (EC 1.2.1.10) are dehydrogenase enzymes which catalyze the conversion of acetaldehyde into acetyl-CoA. This can be summarized as follows: Acetaldehyde + NAD + + Coenzyme A ↔ Acetyl-CoA + NADH + H +. In humans, there are three known genes which encode this enzymatic activity, ALDH1A1, ALDH2, and the more recently ...
The protein encoded by this gene is a dimeric enzyme that catalyzes the reversible isomerization of G6P and F6P. [12] [13] Since the reaction is reversible, its direction is determined by G6P and F6P concentrations. [9] glucose 6-phosphate ↔ fructose 6-phosphate. The protein has different functions inside and outside the cell.
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).
