Notes:
A mutant of BHK cells (ts422E) temperature-sensitive for processing 32S rRNA to 28S rRNA (Toniolo et al., '73) also loses the ability to synthesize polyamines and 5.8S rRNA when shifted to the non-permissive temperature (39°). The activity of several enzymes not involved with polyamine synthesis, methylation of 32S rRNA, and small nuclear RNA production are apparently unaffected after at least 24 hours at 39°. When cultures are returned to the permissive temperature (33°), polyamine synthesizing capacity returns to normal as mature rRNA production resumes.
