additional information

Escherichia coli

residues C291 and C294 of the C291XXC294XXC297 motif undergo reversible disulfide formation, which regulates the activity of the enzyme. Disulfide-bond formation and reduction are effected by oxidized and reduced forms of thioredoxin, with a midpoint potential of -264 mV for the redox couple
