Two kinds of yeast secretion vectors were constructed by site-directed mutagenesis of the invertase signal sequence and ligation of synthetic oligonucleotides coding appropriate signals. Each has a cloning site for a foreign gene preceded by a sequence encoding either the signal peptide cleavage site or a Lys-Arg sequence which is a cleavage site for the product of the KEX2 gene. Both vectors were able to direct the expression and secretion of mouse amylase. One of them has a SalI site within the signal sequence, and an attempt to clone sequences enhancing secretion of amylase with this vector is reported.
