Abstract

We developed a methylotrophic yeast, Pichia pastoris, as a host for DNA transformations. The system is based on an auxotrophic mutant host of P. pastoris which is defective in histidinol dehydrogenase. As a selectable marker, we isolated and characterized the P. pastoris HIS4 gene. Plasmid vectors which contained either the P. pastoris or the Saccharomyces cerevisiae HIS4 gene transformed the P. pastoris mutant host. DNA transfer was accomplished by a modified version of the spheroplast generation (CaCl2-polyethylene glycol)-fusion procedure developed for S. cerevisiae. In addition, we report the isolation and characterization of P. pastoris DNA fragments with autonomous replication sequence activity. Two fragments, PARS1 and PARS2, when present on plasmids increased transformation frequencies to 10(5)/micrograms and maintained the plasmids as autonomous elements in P. pastoris cells.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
