AU RNA binding methylglutaconyl-CoA hydratase

This bifunctional mitochondrial protein serves as methylglutaconyl-CoA hydratase, catalyzing the hydration of 3-methylglutaconyl-CoA to 3-hydroxy-3-methyl-glutaryl-CoA in the leucine degradation pathway, and also binds AU-rich elements in mRNA 3' UTRs to regulate RNA degradation. Mutations cause 3-methylglutaconic aciduria type I through autosomal recessive inheritance, resulting from deficient hydratase activity that disrupts leucine catabolism.
