Protein

Methylmalonyl-CoA mutase small subunit

Gene

mutA

Organism
Propionibacterium freudenreichii subsp. shermanii
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the isomerization of succinyl-CoA to methylmalonyl-CoA during synthesis of propionate from tricarboxylic acid-cycle intermediates.

Catalytic activityi

(R)-methylmalonyl-CoA = succinyl-CoA.

Cofactori

Pathwayi: propanoyl-CoA degradation

This protein is involved in step 3 of the subpathway that synthesizes succinyl-CoA from propanoyl-CoA.
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. no protein annotated in this organism
  2. no protein annotated in this organism
  3. Methylmalonyl-CoA mutase large subunit (mutB), Methylmalonyl-CoA mutase small subunit (mutA)
This subpathway is part of the pathway propanoyl-CoA degradation, which is itself part of Metabolic intermediate metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes succinyl-CoA from propanoyl-CoA, the pathway propanoyl-CoA degradation and in Metabolic intermediate metabolism.
