5.A.1.2.9 CcdA family member, the thiol:disulfide excange protein, DipZ of 695 aas and 7 TMSs. The 1.9Å resolution x-ray structure of the C-terminal ectodomain of Rv2874 revealed the predicted thioredoxin-like domain with its
conserved Cys-X-X-Cys active-site motif, but this domain is combined with a second domain
with a carbohydrate-binding module (CBM) fold (Goldstone et al. 2016). A cavity in the CBM adjacent to the thioredoxin
active site suggested the presence of a carbohydrate-binding site. Possibly, this allows an expansion of the thioredoxin-domain functionality to
carbohydrate modification.
