CommentMembers of this family, hydroxyisourate hydrolase, represent a distinct clade of transthyretin-related proteins. Bacterial members typically are encoded next to ureidoglycolate hydrolase and often near either xanthine dehydrogenase or xanthine/uracil permease genes and have been demonstrated to have hydroxyisourate hydrolase activity [1]. In eukaryotes, a clade separate from the transthyretins (a family of thyroid-hormone binding proteins) has also been shown to have HIU hydrolase activity in urate catabolizing organisms [2]. Transthyretin, then, would appear to be the recently diverged paralog of the more ancient HIUH family.
