This family consists of taurine catabolism dioxygenases of the TauD, TfdA family. TauD from E. coli Swiss:P37610 is a alpha-ketoglutarate-dependent taurine dioxygenase [1]. This enzyme catalyses the oxygenolytic release of sulfite from taurine [1]. TfdA from Burkholderia sp. Swiss:Q45423 is a 2,4-dichlorophenoxyacetic acid/alpha-ketoglutarate dioxygenase [2]. TfdA from Alcaligenes eutrophus JMP134 Swiss:P10088 is a 2,4-dichlorophenoxyacetate monooxygenase [3]. Also included are gamma-Butyrobetaine hydroxylase enzymes EC:1.14.11.1 [4].
