Metabolite Identification
Common NameIduronic acid
DescriptionIduronic acid is a constituent of glycosaminoglycans heparin and heparan sulfate in varying proportions providing considerable diversity in sequence and biological function. The glycosaminoglycans (GAGs) are linear polysaccharides with alternating uronic acids (Iduronic acid and Glucuronic acid) and hexosamine residues, in which a limited set of monosaccharide units gives rise to a number of complex sequences by variable substitution with O-sulfate, N-sulfate, and N-acetyl groups. GAGs usually exist as the O-linked side-chains of proteoglycans, displaying a set of physiological functions which is remarkably wide and as yet incompletely explored. They may act as structural components of connective tissue and the extracellular matrix, or as specific ligands in the relationship between the cell surface and its surroundings. Heparan sulfate exists on the surface of most or all mammalian cells and can display a remarkable range of different sequence motifs; its range of interactions and possible functions reflect its structural complexity. The main repeat unit of heparin structurally resembles the protein binding sequences in heparan sulfate, but contains a higher percentage of sulfated residues. Utilized therapeutically as an anticoagulant and readily available in good quantities heparin serves as a useful model for heparan sulfate. Theoretical and experimental studies indicate that L-Iduronic acid residues of glycosaminoglycans are in equilibrium of different conformations, the relative proportion of conformers being a function of sulfation pattern and sequence. This unique conformational flexibility may provide an explanation for the stronger binding and associated higher biological activities of Iduronic acid-containing glycosaminoglycans (such as heparin, heparan sulfate and dermatan sulfate) as compared with other GAGs having similar charge density but with the more rigid glucuronic acid as the major uronic acid residue. Dermatan sulfates and heparins, which contain L-Iduronic acid in their backbone, show higher low-density lipoprotein (LDL)-affinity than chondroitin sulfates, which contain only D-glucuronic acid. Though confirming a non-specific, predominantly electrostatic interaction between GAGs and LDL, these results indicate modulation of LDL affinity by the polysaccharide backbone. Naturally oversulfated dermatan sulfate (SO3H/COOH ca. 1.2), mainly oversulfated at C-2 of Iduronic acid residues, show comparatively higher anticoagulant activity.

Enzymes

Enzyme Details
1. Heparan sulfate glucosamine 3-O-sulfotransferase 3B1
General function:
Involved in sulfotransferase activity
Specific function:
Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) to catalyze the transfer of a sulfo group to an N-unsubstituted glucosamine linked to a 2-O-sulfo iduronic acid unit on heparan sulfate. Catalyzes the O-sulfation of glucosamine in IdoUA2S-GlcNS and also in IdoUA2S-GlcNH2. The substrate-specific O-sulfation generates an enzyme-modified heparan sulfate which acts as a binding receptor to Herpes simplex virus-1 (HSV-1) and permits its entry. Unlike 3-OST-1, does not convert non-anticoagulant heparan sulfate to anticoagulant heparan sulfate.
Gene Name:
HS3ST3B1
Uniprot ID:
Q9Y662
Molecular weight:
43323.605

5. UDP-glucuronosyltransferase 2B4
General function:
Involved in transferase activity, transferring hexosyl groups
Specific function:
UDPGTs are of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isozyme is active on polyhydroxylated estrogens (such as estriol, 4-hydroxyestrone and 2-hydroxyestriol) and xenobiotics (such as 4-methylumbelliferone, 1-naphthol, 4-nitrophenol, 2-aminophenol, 4-hydroxybiphenyl and menthol). It is capable of 6 alpha-hydroxyglucuronidation of hyodeoxycholic acid.
Gene Name:

6. UDP-glucuronosyltransferase 1-4
General function:
Involved in transferase activity, transferring hexosyl groups
Specific function:
UDPGT is of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isoform glucuronidates bilirubin IX-alpha to form both the IX-alpha-C8 and IX-alpha-C12 monoconjugates and diconjugate.
Gene Name:
UGT1A4

P22310
Molecular weight:
60024.535
Enzyme Details
7. UDP-glucuronosyltransferase 2B7
General function:
Involved in transferase activity, transferring hexosyl groups
Specific function:
UDPGT is of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. Its unique specificity for 3,4-catechol estrogens and estriol suggests it may play an important role in regulating the level and activity of these potent and active estrogen metabolites. Is also active with androsterone, hyodeoxycholic acid and tetrachlorocatechol (in vitro).
Gene Name:
