And its gene derived from bacteria belonging to the genus Rhodococcus trimethoprim-resistant dihydrofolate reductase

摘要

PROBLEM TO BE SOLVED: To provide a Rhodococcus bacterium-originating trimethoprim-resistant dihydrofolic acid reductase useful for constructing a vector for Rhodococcus bacteria, especially a vector for self-cloning Rhodococcus rhodochrous, to provide a recombinant vector having the gene, and to provide a transformant or transductant having the vector.;SOLUTION: A protein having an activity for imparting trimethoprim resistance to a host microorganism, or a gene DNA encoding the protein. A gene DNA comprising a DNA encoding a protein having an activity for imparting the trimethoprim resistance to a host microorganism. A recombinant vector having the gene DNA, and a transformant or transductant having the vector.;COPYRIGHT: (C)2006,JPO&NCIPI
