| 摘要 |
The present invention relates to a new pro sequence which permits the synthesis and secretion of heterologous proteins from a yeast cell, more particularly a yeast of the genus Saccharomyces cerevisiae. The new pro sequence is derived from the Phormia terranovae insect defensin A precursor. The present invention relates to an expression cassette, a vector as well as a yeast cell comprising a DNA fragment encoding the said pro sequence and a process for preparing heterologous proteins using such a pro sequence. |
