title: Cloning and sequencing of the ura3 locus of the methylotrophic yeast Hansenula polymorpha and its use for the generation of a deletion by gene replacement.
abstract: The ura3 gene of Hansenula polymorpha was cloned, sequenced and used to generate a ura3 mutant from the wild-type strain of this yeast via integrative mutagenesis. The Tn5 neomycin-resistance marker (neo) under control of the ADH1 promoter from Saccharomyces cerevisiae served as a transformation marker. The results show that gene replacement can be achieved in H. polymorpha, a yeast with a high level of non-homologous integration.
