WebBacterial DHFR enzymes can be effectively targeted while sparing the eukaryotic DHFR due to these sequence changes [47,121]. Recent work examined the evolution of DHFR sequences and identified three crucial areas of human DHFR sequence variation and delineated their impacted on the catalytic mechanism . This study revealed mutations … WebThe two DHFR mutant proteins together render the yeast colonies highly resistant to methotrexate as shown in Figure 1. This is a variation of a complementation assay. When two proteins interact in the mated yeast, the two mutant DHFR proteins are brought together and the resulting yeast is able to survive treatment with methotrexate.
