Enzymes
of Gluconeogenesis
Eleven reactions are catalyzed in glucoenogenesis.
The enzymes involved and the reactions they catalyze are listed
below. Glycolysis uses many of the same enzymes as gluconeogenesis,
but with reversal of reaction direction. Enzymes differing between
glycolysis and gluconeogenesis are marked with an asterisk
(*).
- * Glucose-6-Phosphatase (glycolysis uses Hexokinase)
- Phosphoglucoisomerase
- * Fructose-1,6-Bisphosphatase(glycolysis uses Phosphofructokinase
)
- Fructose-1,6-Bisphosphate
Aldolase
- Triosephosphate
Isomerase
- Glyceradehyde-3-Phosphate
Dehydrogenase
- Phosphoglycerate
Kinase
- Phosphoglycerate
Mutase
- Enolase
- * PEPCK (Glycolysis
uses Pyruvate Kinase )
Pyruvate Carboxylase (Glycolysis
uses Pyruvate Kinase )
