Abstract
Because of the complexity, heterogeneity, and flexibility of the glycans, the structural analysis of glycoproteins has been eschewed until recently, with a few prominent exceptions. This aversion may have branded structural biologists as glycophobics. However, recent technological advancements in glycoprotein expression systems, employing genetically engineered production vehicles derived from mammalian, insect, yeast, and even bacterial cells, have yielded encouraging breakthroughs. The major advance is the active control of glycoform expression of target glycoproteins based on the genetic manipulation of glycan biogenetic pathways, which was previously overlooked, abolished, or considered unmanageable. Moreover, synthetic and/or chemoenzymatic approaches now enable the preparation of glycoproteins with uniform glycoforms designed in a tailored fashion.
