The main area of my expertise concerns protein sorting and secretion in Gram-positive bacteria, such as Bacillus subtilis and Staphylococcus aureus.
The Gram-positive bacterium B. subtilis is well known for its high capacity to secrete proteins into the extracellular milieu, which has led to its exploitation as a "cell factory" for secreted proteins. Nevertheless, the secretion of heterologous proteins of pharmaceutical importance is frequently inefficient. This applied problem has been a major
