Supplementary information

Succinate dehydrogenase complex flavoprotein subunit A (SDHA) also known as complex II Fp or SDH2 plays an important role in the mitochondrial electron transport chain and the tricarboxylic acid (TCA) cycle. It functions as a flavoprotein oxidoreductase catalyzing the oxidation of succinate to fumarate. With a molecular mass of approximately 72 kDa SDHA is expressed in the inner mitochondrial membrane of eukaryotic cells where it is a core component of the succinate dehydrogenase complex (SDHC). The complex is essential for cellular respiration and energy production.
Biological function summary

SDHA participates in the TCA cycle by accepting electrons from succinate which it donates to the coenzyme Q in the electron transport chain. This essential role connects SDHA to the regulation of ATP production in cells. SDHA operates as part of the larger succinate dehydrogenase (SDH) complex which includes other subunits such as SDHB SDHC and SDHD. This structurally integrated multisubunit complex influences mitochondrial integrity and cellular energy homeostasis.

Pathways

SDHA is deeply involved in the TCA cycle and oxidative phosphorylation pathway. As a part of these pathways it links to other critical enzymes such as fumarase and aconitase working in concert to drive the conversion of biochemical fuel into usable cellular energy. Its interactions with coenzyme Q and cytochrome complex enzymes are important for electron flow and proton gradient formation across the mitochondrial membrane. Such interactions are central to cellular respiration and energy generation.

Mutations in SDHA correlate with various mitochondrial diseases and cancer syndromes. Specifically SDHA mutations have an association with Leigh syndrome and certain types of mitochondrial complex II deficiency. These mutations disrupt the function of the SDH complex causing metabolic imbalances and energy production issues. Furthermore the integral interaction of SDHA with other SDH subunits means that alterations can impact this entire enzymatic complex with implications for cellular respiration and disease progression.

Target data

Flavoprotein (FP) subunit of succinate dehydrogenase (SDH) that is involved in complex II of the mitochondrial electron transport chain and is responsible for transferring electrons from succinate to ubiquinone (coenzyme Q) (PubMed : 10746566, PubMed : 24781757). SDH also oxidizes malate to the non-canonical enol form of oxaloacetate, enol-oxaloacetate (By similarity). Enol-oxaloacetate, which is a potent inhibitor of the succinate dehydrogenase activity, is further isomerized into keto-oxaloacetate (By similarity). Can act as a tumor suppressor (PubMed : 20484225).
