A member of the deaminase fold that binds an unknown ligand in the crystal structure. The protein is ADP-ribosylated at a conserved aspartate [1]. Contextual analysis suggests that the domain is likely to bind NAD or ADP ribose either to sense redox states or to function as a regulatory ADP ribosyltransferase [2].	Domain
