A protein complex capable of catalyzing the conversion of taurine and alpha-ketoglutarate to sulfite, aminoacetaldehyde and succinate under sulfur or cysteine starvation conditions. Its expression is repressed by the presence of sulfate or cysteine. In E. coli it is a homodimer or homotetramer of the protein TauD.
alpha-ketoglutarate-dependent taurine dioxygenase complex
