WebThe only enzyme of known function showing some similarity with XanA is the E. coliα‐KG‐dependent taurine dioxygenase (TauD) (Eichhorn et al., 1997). While the overall similarity is very low, we found putative Fe(II) binding sites which are similar to those found in the α‐KG‐dependent dioxygenases. high note consulting llc
