摘要:
The expression vectors and methods using an E. coli expression system for the large scale production of IL-21 are described. The vectors utilize the IL-21 coding sequence with specific changes in nucleotides in order to optimize codons and mRNA secondary structure for translation in E. coli. Using the expression vectors, the IL-21 gene was produced in E. coli to a level of greater than 1 g/L in fed batch fermentation. Also included are OmpT deficient E. coli strains transformed with an IL-21 expression vector.

摘要:
Methods for transforming Pichia methanolica, and DNA molecules useful in transformation of P. methanolica, are disclosed. P. methanolica cells are exposed, in the presence of DNA molecules, to a pulsed electric field having a field strength of from 2.5 to 4.5 kV/cm and a pulse duration of from 1 to 40 milliseconds, whereby the DNA molecules are introduced into the cells. The DNA molecules may comprise an expression unit that includes a transcription promoter of a P. methanolica gene operably linked to a segment encoding a polypeptide or protein of interest. The DNA molecules may also encode a selectable marker, such as a P. methanolica ADE2 gene. Cells transformed according to the invention may be used in production systems for the preparation of proteins of commercial importance.
