초록
Cloning of the gene encoding extracellular .betha.-lactamase from Streptomyces sp. SMF13 in a plasmid pIJ702 and expression of the gene in Streptomyces invidans were carried out. Optimal conditions for the formation of protoplasts of S.lividans and the regeneration of the protoplasts were evaluated. Streptomyces sp. SMF-13 was selected as a donor strain of .betha.-lactamase gene and totla DNA of the strain was partially digested with Sau3A I. DNA fragments ranged from 4kb to 10 kb were ligated to pIJ702 AT Bgl II site and then the ligated DNAs were transformed to the protoplasts of S, livivans. The transformation efficiency was
