Abstract

See full text

It is intended to provide a process for efficiently producing a recombinant protein free from the N-terminal methionine. In culturing a host transformed by an expression vector for expressing a gene-modified protein, the dissolved oxygen concentration in the liquid culture medium is controlled to about 1 ppm or lower. Thus, the ratio of the expression of a recombinant protein free from the N-terminal methionine is elevated compared with the case wherein no such control is performed.
