Succinic acid (YMDB00338)

Identification
YMDB IDYMDB00338
NameSuccinic acid
SpeciesSaccharomyces cerevisiae
StrainBaker's yeast
DescriptionSuccinic acid, also known as ethylenesuccinate or butanedionic acid, belongs to the class of organic compounds known as dicarboxylic acids and derivatives. These are organic compounds containing exactly two carboxylic acid groups. Succinic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Succinic acid exists in all living species, ranging from bacteria to humans. Succinic acid is a potentially toxic compound.

SDH1 and SDH2 form the catalytic dimer. Electrons flow from succinate to the FAD bound to SDH1, and sequentially through the iron-sulfur clusters bound to SDH2 and enter the membrane dimer formed by SDH3 and SDH4
Gene Name:
