The present invention relates to the sporulation-dependent promoter of the exoproteinase from B. thuringiensis (B.t), including its mutants, variants and homologues which are capable of functioning. It additionally relates to DNA fragments, transgenic cells and vectors which contain said promoter, and to the use of said promoter in regulatory sequences or for the regulation of the expression of homologous or, preferably, heterologous DNA. |
