Thioredoxin-Like Folds.
Ribbon diagrams represent (A) COG3019 rosetta model (DECOY_676), (B) bacterial disulfile oxidoreductase NrdH (1h75),
and (C) E. coli
arsenate reductase ArsC (1j9b). Corresponding secondary structural elements are colored identically in rainbow from
the N-terminus to the C-terminus of the thioredoxin-like fold. Elements corresponding to inserted domains are
white. Residues conserved between all three groups, which are involved in disulfide exchange, are depicted as
a large red ball-and-stick. Residues conserved among individual groups are depicted as a ball-and-stick. The
orange sphere in ArsC represents a sulfate ion and depicts the active site.
