Protein

Malate synthase G

Gene

glcB

Organism
Rhodococcus fascians
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-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 (icl)
  2. 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.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
