Functionⁱ

Catalytic activityⁱ

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

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:

no protein annotated in this organism
Glucose-6-phosphate isomerase (pgi)
ATP-dependent 6-phosphofructokinase (pfkA)
no protein annotated in this organism

This subpathway is part of the pathway glycolysis, which is itself part of Carbohydrate degradation.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose, the pathway glycolysis and in Carbohydrate degradation.
