We have inserted a DNA fragment composed of (i) the promoter and the export signal of the Bacillus subtilis levansucrase gene; (ii) the sequence encoding the mature part of the Clostridium thermocellum endoglucanase A gene in a specific site of the B. subtilis chromosome. The insert was flanked by directly repeated pBR322 sequences of 3.9 kb. Plasmid pE194, which has a thermosensitive replication, was integrated adjacent to one of the repeats. When the integrated plasmid was allowed to replicate, the insert and one of the repeats was amplified up to a level of about 250 copies per chromosome. Endoglucanase A was efficiently synthesized in, and secreted from, cells containing the amplified structure, since the heterologous fusion protein was the major extracellular protein in a B. subtilis sacUh strain. The NH2-terminal sequence of the secreted protein revealed three different cleavage sites in the vicinity of the signal peptidase recognition sequence.
