This model represents a protein that is predominantly found just upstream of the UraD protein (OHCU decarboxylase) and in a number of instances as a N-terminal fusion with it. UraD itself catalyzes the last step in the catabolism of urate to allantoate. The function of this protein is presently unknown. It shows homology with the pfam01522 polysaccharide deacetylase domain family.
