Plasmid vectors for expression in escherichia coli and/or bacillus subtilis

摘要

Novel plasmid vectors are described, for expression in Escherichia coli and/or Bacillus subtilis, in which the gene which codes for a heterologous protein is placed under the control of a promoter of the erythromycin gene which permit the organisms transformed with the abovementioned plasmids to express the heterologous protein in high yields.
