Post-transcriptional regulation of glutamyl-prolyl-tRNA synthetase in rat salivary gland.


Treatment of rats with isoproterenol resulted in elevated levels of prolyl- and glutamyl-tRNA synthetase activities in the parotid and submandibular glands. This increase in enzyme activity was accompanied by an increase in the bi-functional glutamyl-prolyl-tRNA synthetase and of a low molecular weight form of prolyl-tRNA synthetase. Isoproterenol also… (More)
