The disclosure relates to the field of glyco-engineering, more specifically, to eukaryotic cells wherein both an endoglucosaminidase and a glycoprotein are present. These cells can be used to deglycosylate or partly deglycosylate the (exogenous) glycoprotein, in particular, without the need for adding an extra enzyme. Methods are also provided for the application of these cells in protein production. According to one specific aspect, the eukaryotic cells are glyco-engineered yeast cells in which, additionally, at least one exogenous enzyme needed for complex glycosylation is present, e.g., allowing easier separation of differentially glycosylated glycoproteins.
