摘要:
The present invention relates to a method of expressing a gene by inserting the genome into a host organism using genetic engineering techniques. The present invention further relates to a novel promoter, a recombinant vector containing the promoter and a target gene, a transformant containing the recombinant vector, and a method of producing a useful gene product or useful substance using the transformant.
摘要:
The present invention provides a transformant into which has been incorporated DNA for coding a foreign protein having lactate dehydrogenase activity and provided with pyruvic acid substrate affinity that equals or exceeds the pyruvic acid substrate affinity of the pyruvate decarboxylase inherent in the host organism. Said transformant can stably mass-produce lactic acid inside a host organism having the pyruvate decarboxylase gene.
