1. A method of producing a plant cell expressing a heterologous glycoprotein that is reduced in xylose and fucose, comprising introducing into the plant cell a first expression cassette and a second expression cassette, wherein the first expression cassette comprises a nucleic acid comprising SEQ ID No:3 encoding a hybrid enzyme, and the second expression cassette comprises nucleic acid encoding a heterologous glycoprotein, and expressing the hybrid enzyme and the heterologous glycoprotein, wherein the expressed glycoprotein is reduced in xylose and fucose when compared to a glycoprotein expressed in a plant cell in the absence of the hybrid enzyme.
