Protein

Malate synthase G

Gene

glcB

Organism
Escherichia coli O6:H1 (strain CFT073 / ATCC 700928 / UPEC)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Involved in the glycolate utilization. Catalyzes the condensation and subsequent hydrolysis of acetyl-coenzyme A (acetyl-CoA) and glyoxylate to form malate and CoA.UniRule annotation

Catalytic activityi

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

Cofactori

Mg2+UniRule annotation

Pathwayi: glyoxylate cycle

This protein is involved in step 2 of the subpathway that synthesizes (S)-malate from isocitrate.UniRule annotation
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Isocitrate lyase (aceA)
  2. Malate synthase G (glcB), Malate synthase (aceB)
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.
