Protein
Methylcrotonoyl-CoA carboxylase subunit alpha, mitochondrial
Gene
MCCA
Organism
Glycine max (Soybean) (Glycine hispida)
Status
Functioni
Biotin-attachment subunit of the 3-methylcrotonyl-CoA carboxylase, an enzyme that catalyzes the conversion of 3-methylcrotonyl-CoA to 3-methylglutaconyl-CoA, a critical step for leucine and isovaleric acid catabolism.By similarity
Catalytic activityi
- 3-methyl-(2E)-butenoyl-CoA + ATP + hydrogencarbonate = ADP + H+ + phosphate + trans-3-methylglutaconyl-CoAEC:6.4.1.4
Cofactori
Protein has several cofactor binding sites:: L-leucine degradation Pathwayi
This protein is involved in step 2 of the subpathway that synthesizes (S)-3-hydroxy-3-methylglutaryl-CoA from 3-isovaleryl-CoA.Proteins known to be involved in the 3 steps of the subpathway in this organism are:
- no protein annotated in this organism
- Methylcrotonoyl-CoA carboxylase subunit alpha, mitochondrial (MCCA)
- no protein annotated in this organism
View all proteins of this organism that are known to be involved in the subpathway that synthesizes (S)-3-hydroxy-3-methylglutaryl-CoA from 3-isovaleryl-CoA, the pathway L-leucine degradation and in Amino-acid degradation.
