This domain is found at the C-terminal end of Protein adenylyltransferase SoFic from Shewanella oneidensis and similar bacterial sequences. SoFic mediates the addition of adenosine 5'-monophosphate (AMP) to specific residues of target proteins. This is a winged-helix DNA-binding domain often found associated with Pfam:PF02661 [1-3].
