Over 10\u2003000 new victims are reported each year, with hundreds of thousands more at risk. As current drug treatments are either highly toxic or ineffective, novel trypanocides are urgently needed. The <jats:italic>T.\u00a0brucei<\/jats:italic> galactose synthesis pathway is one potential therapeutic target. Although galactose is essential for <jats:italic>T.\u00a0brucei<\/jats:italic> survival, the parasite lacks the transporters required to intake galactose from the environment. UDP\u2010galactose 4\u2032\u2010epimerase (<jats:italic>Tb<\/jats:italic>GalE) is responsible for the epimerization of UDP\u2010glucose to UDP\u2010galactose and is therefore of great interest to medicinal chemists. Using molecular dynamics simulations, we investigate the atomistic motions of <jats:italic>Tb<\/jats:italic>GalE in both the <jats:italic>apo<\/jats:italic> and <jats:italic>holo<\/jats:italic> states. The sampled conformations and protein dynamics depend not only on the presence of a UDP\u2010sugar ligand, but also on the chirality of the UDP\u2010sugar C4 atom. This dependence provides important insights into <jats:italic>Tb<\/jats:italic>GalE function and may help guide future computer\u2010aided drug discovery efforts targeting this protein.<\/jats:p>","DOI":"10.1111\/j.1747-0285.2012.01392.x","type":"journal-article","created":{"date-parts":[[2012,4,5]],"date-time":"2012-04-05T18:48:51Z","timestamp":1333651731000},"page":"173-181","source":"Crossref","is-referenced-by-count":16,"title":["The Molecular Dynamics of <i>Trypanosoma brucei<\/i> UDP\u2010Galactose 4\u2032\u2010Epimerase: A Drug Target for African Sleeping Sickness"],"prefix":"10.1111","volume":"80","author":[{"given":"Aaron J.","family":"Friedman","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jacob D.","family":"Durrant","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Levi C.
