Protein

Methylglutaconyl-CoA hydratase, mitochondrial

Gene

AUH

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the conversion of 3-methylglutaconyl-CoA to 3-hydroxy-3-methylglutaryl-CoA (PubMed:11738050, PubMed:12434311, PubMed:12655555). Also has itaconyl-CoA hydratase activity by converting itaconyl-CoA into citramalyl-CoA in the C5-dicarboxylate catabolism pathway (PubMed:29056341). The C5-dicarboxylate catabolism pathway is required to detoxify itaconate, a vitamin B12-poisoning metabolite (PubMed:29056341). Has very low enoyl-CoA hydratase activity (PubMed:7892223). Was originally identified as RNA-binding protein that binds in vitro to clustered 5'-AUUUA-3' motifs (PubMed:7892223).1 Publication4 Publications

Catalytic activityi

(S)-3-hydroxy-3-methylglutaryl-CoA = trans-3-methylglutaconyl-CoA + H2O.1 Publication
Citramalyl-CoA = itaconyl-CoA + H2O.1 Publication

Pathwayi: L-leucine degradation

This protein is involved in step 3 of the subpathway that synthesizes (S)-3-hydroxy-3-methylglutaryl-CoA from 3-isovaleryl-CoA.1 Publication
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. Isovaleryl-CoA dehydrogenase, mitochondrial (IVD)
  2. Methylcrotonoyl-CoA carboxylase subunit alpha, mitochondrial (MCCC1), Methylcrotonoyl-CoA carboxylase beta chain, mitochondrial (MCCC2)
  3. Methylglutaconyl-CoA hydratase, mitochondrial (AUH)
This subpathway is part of the pathway L-leucine degradation, which is itself part of Amino-acid degradation.
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.

Involvement in diseasei

3-methylglutaconic aciduria 1 (MGA1)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionAn inborn error of leucine metabolism. It leads to an autosomal recessive syndrome with variable clinical phenotype, ranging from delayed speech development to severe psychomotor retardation, coma, failure to thrive, metabolic acidosis and dystonia. MGA1 can be distinguished from other forms of MGA by the pattern of metabolite excretion: 3-methylglutaconic acid levels are higher than those detected in other forms, whereas methylglutaric acid levels are usually only slightly elevated and there is a high level of 3-hydroxyisovaleric acid excretion (not present in other MGA forms).
