Catalytic Activity (S)-3-hydroxy-3-methylglutaryl-CoA = trans-3- methylglutaconyl-CoA + H(2)O.
Disease 3-methylglutaconic aciduria 1 (MGA1) [MIM:250950]: An 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). {ECO:0000269|PubMed:12655555}. Note=The disease is caused by mutations affecting the gene represented in this entry.
Function Catalyzes the conversion of 3-methylglutaconyl-CoA to 3- hydroxy-3-methylglutaryl-CoA. Has very low enoyl-CoA hydratase activity. Was originally identified as RNA-binding protein that binds in vitro to clustered 5'-AUUUA-3' motifs. {ECO:0000269|PubMed:11738050, ECO:0000269|PubMed:12434311, ECO:0000269|PubMed:12655555, ECO:0000269|PubMed:7892223}.
Pathway Amino-acid degradation; L-leucine degradation; (S)-3- hydroxy-3-methylglutaryl-CoA from 3-isovaleryl-CoA: step 3/3.
Similarity Belongs to the enoyl-CoA hydratase/isomerase family. {ECO:0000305}.
Subcellular Location Mitochondrion {ECO:0000250}.
Subunit Homohexamer.
