Zusammenfassung:	Novel vectors are provided for identifying secretory signal sequences from DNA fragments of unicellular microorganisms. The plasmids comprise a multiple cloning site with restriction sites in reading frame with a structural gene which permits rapid screening of the secreted expression product. Optionally, the vectors may include a promoter region upstream from the multiple cloning site. The invention is exemplified with Bacillus. Specific secretory signal sequences have been isolated with those vectors, allowing real secretion of proteins in economically high yields. Certain isolated signal sequences appeared to be much better than the sequences regulating the high yield secretion of known extracellular proteins.
