摘要:
A novel alkaline protease promoter and alkaline protease terminator which each effectively function in a host-vector system of molds can be obtained from yellow koji mold. A gene expression unit comprising the promoter and terminator is used to construct an expression vector capable of expressing an useful substance in molds such as Aspergillus oryzae , Aspergillus niger , Aspergillus awamori , Aspergillus sojae , etc.
