Abstract: A vector for high-level expression of a heterologous gene in Bacillus, including a DNA sequence which encodes all or part of the structural gene and contains the promoter and ribosome binding site of a Bacillus coagulans amylase gene; within or immediately downstream of the structural gene is a site for insertion of heterologous DNA; when inserted, the heterologous DNA is in the same translational reading frame as the amylase gene; the heterologous DNA thus is under control of the B. coagulans amylase gene regulatory elements and expressed at high levels. A signal-encoding sequence may be inserted independent of, or along with, the heterologous DNA leading to authentic secretion of the heterologous protein.
