Dolichyl-phosphate-glucose is flipped toward the luminal side of the ER membrane (Imbach T et al, 1999). The exact mechanism and proteins involved in this step are not clear yet, but it is known that it must be carried out by a different flippase than the one that catalyzes the flipping of the N-glycan precursor (Sanyal S et al, 2008).
