Integrative transformation system for the metabolic engineering of the sphingoid base-producing yeast Pichia ciferrii.

Abstract

We have developed an integrative transformation system for metabolic engineering of the tetraacetyl phytosphingosine (TAPS)-secreting yeast Pichia ciferrii. The system uses (i) a mutagenized ribosomal protein L41 gene of P. ciferrii as a dominant selection marker that confer resistance to the antibiotic cycloheximide and (ii) a ribosomal DNA (rDNA) fragment… (More)
