General annotation (Comments)

Function	Key enzyme in ketogenesis (ketone body formation). Terminal step in leucine catabolism. Ref.7 Ref.13 Ref.14
Catalytic activity	(S)-3-hydroxy-3-methylglutaryl-CoA = acetyl-CoA + acetoacetate. Ref.13 Ref.14
Cofactor	Divalent metal cations. Ref.9
Enzyme regulation	Stimulated by reducing agents such as dithiothreitol (DTT). Ref.9
Pathway	Metabolic intermediate metabolism; (S)-3-hydroxy-3-methylglutaryl-CoA degradation; acetoacetate from (S)-3-hydroxy-3-methylglutaryl-CoA: step 1/1.
Subunit structure	Homodimer; disulfide-linked. Can also form homotetramers. Ref.8 Ref.15
Subcellular location	Mitochondrion matrix. Peroxisome. Note: Unprocessed form is peroxisomal. Ref.6 Ref.8
Tissue specificity	Fibroblasts, liver and lymphoblasts.
Involvement in disease	3-hydroxy-3-methylglutaryl-CoA lyase deficiency (HMGCLD) [MIM:246450]: An autosomal recessive disease affecting ketogenesis and L-leucine catabolism. The disease usually appears in the first year of life after a fasting period and its clinical acute symptoms include vomiting, seizures, metabolic acidosis, hypoketotic hypoglycemia and lethargy. These symptoms sometimes progress to coma, with fatal outcome in some cases. Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.16 Ref.17 Ref.18 Ref.19 Ref.20 Ref.21 Ref.22 Ref.23 Ref.24 Ref.25
Sequence similarities	Belongs to the HMG-CoA lyase family.
Biophysicochemical properties	Kinetic parameters: KM=200 µM for magnesium ion Ref.9 Ref.10 KM=48 µM for HMG-CoA Vmax=191 µmol/min/mg enzyme
