HIUase (5-hydroxyisourate hydrolase) catalyzes the second step in a three-step ureide pathway in which 5-hydroxyisourate (HIU), a product of the uricase (urate oxidase) reaction, is hydrolyzed to 2-oxo-4-hydroxy-4-carboxy-5-ureidoimidazoline (OHCU). HIUase has high sequence similarity with transthyretins and is a member of the transthyretin-like protein (TLP) family. HIUase is distinguished from transthyretins by a conserved signature motif at its C-terminus that forms part of the active site. In HIUase, this motif is YRGS, while transthyretins have a conserved TAVV sequence in the same location. Most HIUases are cytosolic but in plants and slime molds, they are peroxisomal based on the presence of N-terminal periplasmic localization sequences. HIUase forms a homotetramer with each subunit consisting of eight beta-strands arranged in two sheets and a short alpha-helix. The central channel of the tetramer contains two independent binding sites, each located between a pair of subunits. Pssm-ID: 100114 Cd Length: 112 Bit Score: 134.59 E-value: 1.85e-42

HIUase/Transthyretin family; This family includes transthyretin that is a thyroid hormone-binding protein that transports thyroxine from the bloodstream to the brain. However, most of the sequences listed in this family do not bind thyroid hormones. They are actually enzymes of the purine catabolism that catalyze the conversion of 5-hydroxyisourate (HIU) to OHCU. HIU hydrolysis is the original function of the family and is conserved from bacteria to mammals; transthyretins arose by gene duplications in the vertebrate lineage. HIUases are distinguished in the alignment from the conserved C-terminal YRGS sequence. Pssm-ID: 459857 Cd Length: 108 Bit Score: 127.95 E-value: 8.34e-40

hydroxyisourate hydrolase; Members 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. 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. Transthyretin, then, would appear to be the recently diverged paralog of the more ancient HIUH family.

Transthyretin_like. This domain is present in the transthyretin-like protein (TLP) family which includes transthyretin (TTR) and a transthyretin-related protein called 5-hydroxyisourate hydrolase (HIUase). TTR and HIUase are homotetrameric proteins with each subunit consisting of eight beta-strands arranged in two sheets and a short alpha-helix. The central channel of the tetramer contains two independent binding sites, each located between a pair of subunits. TTR transports thyroid hormones and retinol in the blood serum of vertebrates while HIUase catalyzes the second step in a three-step ureide pathway. TTRs are highly conserved and found only in vertebrates while the HIUases are found in a wide range of bacterial, plant, fungal, slime mold and vertebrate organisms.

4-104 | 2.84e-04 | |||
Transthyretin (TTR) is a 55 kDa protein responsible for the transport of thyroid hormones and retinol in vertebrates. TTR distributes the two thyroid hormones T3 (3,5,3'-triiodo-L-thyronine) and T4 (Thyroxin, or 3,5,3',5'-tetraiodo-L-thyronine), as well as retinol (vitamin A) through the formation of a macromolecular complex that includes each of these as well as retinol-binding protein. Misfolded forms of TTR are implicated in the amyloid diseases familial amyloidotic polyneuropathy and senile systemic amyloidosis. TTR forms a homotetramer with each subunit consisting of eight beta-strands arranged in two sheets and a short alpha-helix. The central channel of the tetramer contains two independent binding sites, each located between a pair of subunits, which differ in their ligand binding affinity. A negative cooperativity has been observed for the binding of T4 and other TTR ligands. A fraction of plasma TTR is carried in high density lipoproteins by binding to apolipoprotein AI (apoA-I). TTR is able to proteolytically process apoA-I by cleaving its C-terminus; therefore TTR has protease activity in addition to its function in protein transport.
