Abstract | ||||
The yeast Hapsenula pdymorpha was used as a host for expression of gamma chain peptide of FAb fragment of mouse articreatine kinase-M, IgG antibody. Two expression systems were designed and assembled based on the promoter codon of either of the preferentially highly expressed enzymes, formate dehydrogenase (FMD) and methanol oxidase (MOX) of H. polymorpha. Two expression plasmid vectors, PGAGU and PHAAI, with FMD and MOX promoters, representity, were contsructed and transformed into H. pdymorpha LR9 Expression of gamma chain gene yielded about 400 mg/L and 550 mg/L, respectively 7% and 10% of the total cell protein under the control of FMD and MOX promoters, respectively. The prepro alpha was incompletely processed and most of the gamma chain peptide accumulated within the cells, especially under the control of FMD promoter. | ||||
