A method of effecting a change in a cell using a transfer system which is contacted with the cell to be changed. The transfer system comprises a fusion protein which is transferred into the cell using the VirB/VirD4 transfer system. According to the invention, a fusion protein BA is introduced into the cell to be changed comprising i) as a first part A, an oligopeptide comprising the C-terminal amino acids 1-20 of VirF, VirD2, VirE2, VirE3, VirD5 or MobA, or an analogue thereof and ii) as a second part B, a polypeptide capable of effecting a cell-changing activity in the cell to be changed, wherein the polypeptide is attached with the C-terminal end thereof linked with the N-terminal end of the first part. |
