Functioni

Straight-chain enoyl-CoA thioesters from C4 up to at least C16 are processed, although with decreasing catalytic rate. Has high substrate specificity for crotonyl-CoA and moderate specificity for acryloyl-CoA, 3-methylcrotonyl-CoA and methacrylyl-CoA. It is noteworthy that binds tiglyl-CoA, but hydrates only a small amount of this substrate.1 Publication

Catalytic activityi

Involvement in diseasei

Mitochondrial short-chain enoyl-CoA hydratase 1 deficiency (ECHS1D)6 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA severe, autosomal recessive inborn error affecting valine metabolism. Disease features include brain lesions in the basal ganglia, neurodegeneration, delayed psychomotor development, hypotonia, spasticity, and increased lactic acid in serum and cerebral serum fluid.
