aceB

Functionⁱ

Catalytic activityⁱ

Acetyl-CoA + H₂O + glyoxylate = (S)-malate + CoA.

Pathwayⁱ: glyoxylate cycle

This protein is involved in step 2 of the subpathway that synthesizes (S)-malate from isocitrate.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:

Isocitrate lyase (aceA)
Malate synthase A (aceB), Malate synthase G (glcB)

This subpathway is part of the pathway glyoxylate cycle, which is itself part of Carbohydrate metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes (S)-malate from isocitrate, the pathway glyoxylate cycle and in Carbohydrate metabolism.
