The expression of a hybrid gene encoding an alpha-factor prepro leader peptide-miniproinsulin (MPI) fusion [MPI is the same as the LysArg human insulin precursor described by Thim et al. (1986)] was tested in a series of isogenic yeast strains to investigate the influence of some genetic and physiological factors on heterologous production in yeast. We(More)
We have isolated the tryptophan auxotrophic mutant strain, PK101, of Pichia guilliermondii. This strain is not defective in any of the tryptophan biosynthetic enzymes, but its chrismate mutase, an enzyme of the phenylalanine-tyrosine biosynthesis, is changed. In comparison with the wild type chorismate mutase, the enzyme of PK101 is characterized by a(More)
