ABSTRACT:
The present invention relates to a efficient expression of a protein, particularly, hirudin; a protein precursor comprising a signal sequence and the sequence of aaX-hirudin, wherein aaXis a selected amino acid, and aaXis preferably leucine; to its preparation and use; and to processes for finding signal sequences for secretory expression of any desired protein inE coli; and to processes for the secretory expression of any desired protein inE coli.
