| 摘要 |
DNA constructs, Pichia methanolica cells, and methods for producing polypeptides using the DNA constructs and cells are disclosed. The DNA constructs comprise a transcription promoter of a Pichia methanolica gene, a DNA segment encoding a polypeptide heterologous to P. methanolica, a transcription terminator of a P. methanolica gene, and a selectable marker. P. methanolica cells containing the DNA constructs are used within methods for producing polypeptides heterologous to P. methanolica. DNA molecules comprising transcription promoters of P. methanolica genes are also disclosed.
