InterPro domain: IPR007263

Members of this family have two highly conserved cysteine residues within the DxxCxxC motif at the N-terminal. This motif is conserved in the thiol-disulfide oxidoreductase family [ 1 ]. This family includes At5g50100 (also known as DCC1) from Arabidopsis thaliana, a thioredoxin that modulates ROS homeostasis resulting in de novo shoot initiation and may be involved in the improvement of the capacity of plant regeneration [ 2 ]. Uncharacterised proteins from bacteria are also included in this family.
