Abstract
Abstract A novel promoter, ribosome-binding site-encoding DNA, and a number of signal peptide-encoding DNA sequences are described for use in Bacillus and other host cells. The compounds are useful in constructing expression vectors for use in Bacillus and other host cells and drive expression and secretion of proteins such as nuclease and human growth hormone. In addition, a general method for obtaining cells with increased abilities to express and secrete heterologous gene products is described.
