-
sequence shows two Cys-X2-Cys-His heme c-binding motifs, bifunctional tetrathionate reductase/thiosulphate dehydrogenase
heme
-
the enzyme TSdA is a periplasmic diheme cytochrome c with hemes. Two Cys-X-X-Cys-His heme c binding motifs are present in the sequence. The active site heme (heme 1) is characterized by an unusual His/Cys axial ligation in TsdA enzymes
heme
-
two hemes, heme 1 and heme 2. Distal ligation of CjTsdA Heme 2 is provided by Asn254 and Met255
-
absence of heme groups in the protein
