1. A DNA construct for the secretion, by a Sec-dependent system, of a protein normally secreted by a Sec-independent system, characterized in that it comprises a promoter, a signal sequence recognized by the Sec-dependent secretion system, a DNA sequence coding for a mature protein normally secreted by a Sec-independent system, and a terminator wherein said construct does not contain a multiple cloning site.

13. A process for secreting a protein that is normally secreted by a Sec-independent secretion system, using a Sec-dependent secretion system, comprising
a) providing a DNA sequence coding for said protein, a promoter, a signal sequence recognized by the Sec-dependent secretion system and a terminator; -
b) constructing a DNA construct comprising said DNA sequence, said promoter, said signal sequence and said terminator; c) introducing said construct into a lactic acid bacterium by gene transfer; and d) secreting said protein by the lactic acid bacterium containing said construct. - View Dependent Claims (14)
