WebDec 25, 2001 · (a) Arg-DHFR ts is long-lived at 23 °C but short-lived at 37 °C in both S. cerevisiae and mouse cells. (b) In yeast, Arg-DHFR ts is degraded (at 37 °C) exclusively by the N-end rule pathway, whereas in mouse cells the same protein at the same temperature is degraded by another proteolytic pathway as well. The corresponding mouse-specific ... Webaltered versions of DHFR can be monitored by measuring growth in the dhr1 mutant strain TH5 (ref. 10). This strain has been comple-mented with DHFR from Plasmodium,Cryptosporidium,and human to obtain yeast that is dependent for its growth on the substituted DHFR (refs 11,12). Murine DHFR has been divided at amino acid
