Lividans. Using pIJ903 bearing tsr gene as a vector, the two furthermost fragments of the cluster, 4. 0kb and 1. 5kb in size respectively, were inserted into it. To facilitate the detection of gene replacement, apr gene was placed in the middle of the two inserts. OriT from E coli plasmid RK2 was also incoporated into the vector, therefore, pIJ903 derivatives can be mobilized from E.
