GAGs that do not contain iduronic acid, namely, chondroitin sulfate A and C and hyaluronic acid, did not inhibit infection. A role for iduronic acid-containing GAGs in RSV infection was confirmed by the ability of basic fibroblast growth factor to block infection, because basic fibroblast growth factor binds to GAGs containing iduronic acid.

Iduronic acid

l-Iduronic acid (IUPAC abbr.: IdoA) is the major uronic acid component of the glycosaminoglycans (GAGs) dermatan sulfate, and heparin.It is also present in heparan sulfate, although here in a minor amount relative to its carbon-5 epimer glucuronic acid.

Mark; Abstract All animals and some bacteria can synthesize linear polysaccharides with a backbone of repeating disaccharide units, called glycosaminoglycans (GAGs). The GAGs are either attached to a protein core, as in proteoglycans (PGs), or exist as free polymer chains, as in hyaluronan.

DS-epimerases 1 and 2 (DS-epi1 and 2), in conjunction with DS-4-O-sulfotransferase 1, are the enzymes responsible for iduronic acid biosynthesis and will be the major focus of this review. CS/DS proteoglycans (CS/DS-PGs) are ubiquitously found in connective tissues, basement membranes, and cell surfaces or are stored intracellularly.

It is made up of repeated disaccharide units consisting of 1,4-linked L-iduronic acid and D-glucosamine. The iduronic acid residues are O-sulfated at position 2,

Usually one sugar is a uronic acid (either D-glucuronic acid or L-iduronic acid) and the other is either N -acetylglucosamine or N -acetylgalactosamine. One or both of the sugars contain one or two sulfate residues. Thus each polysaccharide (also called glycosaminoglycan) chain bears many negative charges, either carboxylic or sulphate groups.
