Crystal structure of the Fucosylgalactoside alpha N-acetylgalactosaminyltransferase (GTA, cisAB mutant L266G, G268A) in complex with UDP
Structural highlights
FunctionBGAT_HUMAN This protein is the basis of the ABO blood group system. The histo-blood group ABO involves three carbohydrate antigens: A, B, and H. A, B, and AB individuals express a glycosyltransferase activity that converts the H antigen to the A antigen (by addition of UDP-GalNAc) or to the B antigen (by addition of UDP-Gal), whereas O individuals lack such activity.

Publication Abstract from PubMedGlycosyltransferases are carbohydrate-active enzymes with essential roles in numerous important biological processes. We have developed a new donor analog for galactosyltransferases that locks a representative target enzyme in a catalytically inactive conformation, thus almost completely abolishing sugar transfer. Results with other galactosyltransferases suggest that this unique mode of glycosyltransferase inhibition may also be generally applicable to other members of this important enzyme family. Structural and mechanistic basis for a new mode of glycosyltransferase inhibition.,Pesnot T, Jorgensen R, Palcic MM, Wagner GK Nat Chem Biol. 2010 May;6(5):321-3. Epub 2010 Apr 4.
