<P>PROBLEM TO BE SOLVED: To provide a system for efficiently expressing a fusion protein in a magnetic bacterium. <P>SOLUTION: It is found that the protein is expressed in the bacterium with high efficiency by a promoter of a gene encoding proteins Msp1, Msp2 and Msp3 expressed on a magnetic microparticle membrane of the magnetic bacterium Magnetospirillum magneticum AMB-1. Specific base sequences of promoter regions (Pmsp1, Pmsp2 and Pmsp3) of the gene are provided and even a method for expressing the protein in the bacterium utilizing these promoters is disclosed. Furthermore, there is provided the magnetic microparticle characterized in that the fusion protein of an anchor protein to the objective protein is expressed on the magnetic microparticle membrane and the anchor protein is Mms13. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
