Plant cell having animal-type sugar chain adding function

1 . A plant cell having an animal-type sugar chain adding function, wherein the plant cell has an introduced gene encoding an enzyme derived from an animal, and the enzyme can transfer a fucose residue to a reducing terminal acetylglucosamine residue of a sugar chain of a glycoprotein.

2 . A plant cell according to claim 1 , wherein the enzyme derived from an animal is α1,6-fucosyl transferase.

3 . A plant regenerated from a plant cell according to claim 1 .

4 . A method for producing a plant cell having an animal-type sugar chain adding function, comprising the step of introducing into the plant cell a gene encoding an enzyme derived from an animal, wherein the enzyme can transfer a fucose residue to a reducing terminal acetylglucosamine residue of a sugar chain of a glycoprotein.

5 . A method for producing a glycoprotein having an animal-type sugar chain, comprising the steps of:

transforming a plant cell by introducing into the plant cell a gene encoding an enzyme derived from an animal and a gene encoding an exogenous glycoprotein, wherein the enzyme can transfer a fucose residue to a reducing terminal acetylglucosamine residue of a glycoprotein, and

cultivating the resultant transformed plant cell.

6 . A method for producing a glycoprotein having an animal-type sugar chain, comprising the steps of:

transforming a plant cell by introducing into the plant cell a gene encoding an enzyme capable of transferring a fucose residue to a reducing terminal acetylglucosamine residue and a gene encoding an exogenous glycoprotein, and

expressing the enzyme in a cell organelle.

7 . A glycoprotein having an animal-type sugar chain produced by a method according to claim 6 .

8 . A plant regenerated from a plant cell according to claim 2.
