ABSTRACT:
The plasmid of the present invention contains Leu 2 gene (.beta.-isopropylmaleate dehydrogenase gene) from Saccharomycopsis lipolytica and an autonomously replicating sequence (hereafter referred to as ARS) and can be a shuttle vector between Escherichia coli and Saccharomycopsis lipolytica since it is produced from shuttle vector pVC 1 of Escherichia coli and Saccharomyces cerevisiae. An exogenous useful gene is inserted into the plasmid of the present invention, namely, shuttle vector to transform Escherichia coli, whereby a large quantity of plasmids are obtained. It becomes possible to produce a useful substance in Saccharomycopsis lipolytica as a host using the plasmid.
