Metabolite Identification
Common NameD-2-Hydroxyglutaric acid
DescriptionD-2-Hydroxyglutaric acid, also known as (R)-hydroxyglutarate or (R)-2-hydroxy-pentanedioate, belongs to the class of organic compounds known as short-chain hydroxy acids and derivatives. These are hydroxy acids with an alkyl chain the contains less than 6 carbon atoms. D-2-Hydroxyglutaric acid exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule. D-2-Hydroxyglutaric acid exists in all living organisms, ranging from bacteria to humans. D-2-Hydroxyglutaric acid is a potentially toxic compound. D-2-Hydroxyglutaric acid has been found to be associated with several diseases known as spondyloenchondrodysplasia and d, l-2-hydroxyglutaric aciduria; also d-2-hydroxyglutaric acid has been linked to the inborn metabolic disorders including d-2-hydroxyglutaric aciduria.

Enzymes

General function:
Energy production and conversion
Specific function:
Catalyzes the cofactor-independent reversible oxidation of gamma-hydroxybutyrate (GHB) to succinic semialdehyde (SSA) coupled to reduction of 2-ketoglutarate (2-KG) to D-2-hydroxyglutarate (D-2-HG). L-3-hydroxybutyrate (L-3-OHB) is also a substrate for HOT when using 2-KG as hydrogen acceptor, resulting in the formation of D-2-HG (By similarity).
