ABSTRACT:
This present invention provides a vector for expression and secretion of a polypeptide by directly joining a DNA sequence coding for a signal peptide to a DNA sequence coding for the desired polypeptide, the vector containing the DNA sequence coding for the signal peptide, a vector for expression and secretion of the desired polypeptide as defined above and further having incorporated therein the DNA sequence coding for the desired polypeptide, a microorganism transformed by the secretion vector, and a process for producing the desired polypeptide by growing the microorganism.
