Characterization of a R plasmid-associated, trimethoprim-resistant dihydrofolate reductase and determination of the nucleotide sequence of the reductase gene.

The trimethoprim-resistant dihydrofolate reductase associated with the R plasmid R388 was isolated from strains that over-produce the enzyme. It was purified to apparent homogeneity by affinity chromatography and two consecutive gel filtration steps under native and denaturing conditions. The purifi...
