In the last 50 years molecular biology was dominated by the exploration of proteins and nucleic acids. Beside their role in energy metabolism, oligos- charides, which represent thethirdclass ofbiomacromolecules, have received less attention. Today it is well established that oligosaccharides are involved in many important biologicalregulation and recognition processes fromp- tein folding to cell cell communication. Glycosylation of proteins is the most complexformofco-andposttranslationalmodi?cation. Thedeterminationof structure-function relationships, however, remains dif?cult due to the...
