A Lactococcus lactis strain deficient in both its major proteases, intracellular (ClpP) and extracellular (HtrA), was constructed and characterized. This strain, hereafter called clpP-htrA, could be obtained only by conjugation between a clpP donor strain and an htrA recipient strain in the NZ9000 context, allowing heterologous gene expression under the control of the NICE (nisin-controlled expression) system....
