Protein
Organism
Escherichia coli (strain K12)
Pharmacological action
unknown
General Function:
Taurine dioxygenase activity
Specific Function:
Catalyzes the conversion of taurine and alpha ketoglutarate to sulfite, aminoacetaldehyde and succinate. Required for the utilization of taurine (2-aminoethanesulfonic acid) as an alternative sulfur source. Pentane-sulfonic acid, 3-(N-morpholino)propanesulfonic acid and 1,3-dioxo-2-isoindolineethanesulfonic acid are also substrates for this enzyme.
