    摘要: Heterologous protein secretion from Gram-positive bacteria, in particular from Bacilli has, with few exceptions, met with little success. Incompatibility of the heterologous proteins with the protein secretion machinery of the host is the main cause of this effect. This limiting factor for the production of heterologous proteins in commercially significant concentrations from Bacillus subtilis is removed by overexpressing the Bacillus subtilis protein FtsY or FtsY protein in combination with overexpression of other members of the bacterial signal recognition particle. Said gene(s) is(are) overexpressed in Bacillus host cells expressing a heterologous protein which then shows an increased amount of the heterologous protein secreted in the surrounding medium.

    摘要: A new expression system is provided which comprises component(s) of a lipase regulation cascade. the lipase regulation cascade as disclosed herein includes a kinase, a DNA binding regulator, a polymerase, a promoter, an upstream activating sequence, and secretion factors. Plasmids and transformed cells are also provided as well as methods of transforming host cells using the plasmids. Further, there is provided a kinase that can regulate the expression of a protein, a DNA binding regulator that can regulate the expression of a protein, a Pseudomonas alcaligenes polymerase, a Pseudomonas alcaligenes sigma 54 promoter, a Pseudomonas alcaligenes upstream activating sequence, the Pseudomonas alcaligenes secretion factors XcpP, XcpQ, XcpR, XcpS, XcpT, XcpU, XcpV, XcpW, XcpX, XcpY, XcpZ and the xcp regulators OrfV, OrfX.
