Previous GeneCards Identifiers for PDHB Gene
The pyruvate dehydrogenase (PDH) complex is a nuclear-encoded mitochondrial multienzyme complex that catalyzes the overall conversion of pyruvate to acetyl-CoA and carbon dioxide, and provides the primary link between glycolysis and the tricarboxylic acid (TCA) cycle. The PDH complex is composed of multiple copies of three enzymatic components: pyruvate dehydrogenase (E1), dihydrolipoamide acetyltransferase (E2) and lipoamide dehydrogenase (E3). The E1 enzyme is a heterotetramer of two alpha and two beta subunits. This gene encodes the E1 beta subunit. Mutations in this gene are associated with pyruvate dehydrogenase E1-beta deficiency. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Mar 2012]
GeneCards Summary for PDHB Gene
PDHB (Pyruvate Dehydrogenase (Lipoamide) Beta) is a Protein Coding gene. Diseases associated with PDHB include Pyruvate Dehydrogenase E1-Beta Deficiency and Pyruvate Dehydrogenase E1-Alpha Deficiency. Among its related pathways are Glucagon signaling pathway and Respiratory electron transport, ATP synthesis by chemiosmotic coupling, and heat production by uncoupling proteins.. GO annotations related to this gene include pyruvate dehydrogenase (acetyl-transferring) activity and pyruvate dehydrogenase activity. An important paralog of this gene is BCKDHB.
UniProtKB/Swiss-Prot for PDHB Gene
The pyruvate dehydrogenase complex catalyzes the overall conversion of pyruvate to acetyl-CoA and CO(2), and thereby links the glycolytic pathway to the tricarboxylic cycle.
