Functioni

Catalytic activityi

D-glucose 6-phosphate = D-fructose 6-phosphate.UniRule annotation

Pathwayi: gluconeogenesis

This protein is involved in the pathway gluconeogenesis, which is part of Carbohydrate biosynthesis.UniRule annotation
View all proteins of this organism that are known to be involved in the pathway gluconeogenesis and in Carbohydrate biosynthesis.

Pathwayi: glycolysis

This protein is involved in step 2 of the subpathway that synthesizes D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose.UniRule annotation
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. no protein annotated in this organism
  2. Glucose-6-phosphate isomerase (pgi)
  3. ATP-dependent 6-phosphofructokinase (pfkA)
  4. no protein annotated in this organism
This subpathway is part of the pathway glycolysis, which is itself part of Carbohydrate degradation.
