Effect of temperature on arginine incorporation by ribosomeless extracts of cells transformed by a temperature-sensitive mutant of Rous sarcoma virus. 1977

P Rao, and H Kaji

The effect of transformation of normal rat kidney cells by a temperature-sensitive mutant of the Prague strain of Rous sarcoma virus (ts LA 24 PR-A) on the post-translational addition of arginine to the NH2-terminus of preformed acceptor molecules has been studied. Cells maintained at the permissive (35 degrees C) temperature show a high arginine-incorporating activity in ribosome free extracts compared to that found in extracts of cells grown at the non-permissive (40 degrees C) temperature. Temperature shift experiments as well as studies with cells transformed by wild type Rous sarcoma virus suggest that the decreased activity in cells grown at 40 degrees C is not due to a high temperature per se. The lower arginine incorporation in the 40 degrees C cell extracts is partially due to a decrease in the activity of arginyl transferase which catalyses the transfer of arginine from arginyl tRNA to the acceptor protein. Polyacrylamide gel electrophoresis of the radioactive product shows that the acceptor molecules present in extracts of cells grown at 40 degrees C are larger and qualitatively different from those found in extracts of cells grown at 35 degrees C.
