'''Clostridium difficile Toxin A Fragment Bound to aGal(1,3)bGal(1,4)bGlcNAc'''
===Clostridium difficile Toxin A Fragment Bound to aGal(1,3)bGal(1,4)bGlcNAc===




==Overview==
<!--  
Clostridium difficile TcdA is a large toxin that binds carbohydrates on intestinal epithelial cells. A 2-A resolution cocrystal structure reveals two molecules of alpha-Gal-(1,3)-beta-Gal-(1,4)-beta-GlcNAcO(CH(2))(8)CO(2)CH(3) binding in an extended conformation to TcdA. Residues forming key contacts with the trisaccharides are conserved in all seven putative binding sites in TcdA, suggesting a mode of multivalent binding that may be exploited for the rational design of novel therapeutics.
The line below this paragraph, {{ABSTRACT_PUBMED_16622409}}, adds the Publication Abstract to the page
(as it appears on PubMed at http://www.pubmed.gov), where 16622409 is the PubMed ID number.
