1. A method for recombinantly producing a neutral protease, the method comprising the steps of
(a) providing in an expression vector a DNA with a sequence encoding a preproenzyme comprising the amino acid sequence of SEQ ID NO:5, and transforming a host organism with the expression vector, thereby obtaining a transformed host organism, wherein the host organism is a gram-positive prokaryotic species; followed by
(b) expressing the DNA in the transformed host organism, wherein the transformed host organism secretes the neutral protease as a proteolytic processing product of said preproenzyme; followed by
(c) isolating the secreted neutral protease;
thereby recombinantly producing the neutral protease, and
wherein the gram-positive prokaryotic species is Bacillus amyloliquefaciens.
