| evolution | the enzyme belongs to the 5-hydroxyisourate hydrolase/transthyretin superfamily: evolutionary and functional analyses, overview. Teleosts have highly diverged genomes that resulted from whole genome duplication, which leads to an extensive diversity of paralogous genes. Transthyretin, an extracellular thyroid hormone binding protein, is thought to have evolved from an ancestral 5-hydroxyisourate hydrolase by gene duplication at some stage of chordate evolution. Phylogenetic analysis of the teleost aa sequences reveals the presence of two HIUHase subfamilies, HIUHase 1 (which has an N-terminal peroxisomal targeting signal-2) and HIUHase 2 (which does not have an N-terminal PTS2), and one transthyretin family | Oncorhynchus mykiss |
| metabolism | the enzyme catalyzes the hydrolysis of 5-hydroxyisourate in the purine degradation pathway, and transthyretin, a thyroid hormone binding protein | Oncorhynchus mykiss |
