Yeast proteinase yscB inactivates the leucyl tRNA synthetase in extracts of Saccharomyces cerevisiae.

Biochimica et biophysica acta - 9 Apr 1991

Larrinoa I F, Heredia C F

Abstract excerpt

The aminoacyl-tRNA synthetases are inactivated in extracts of Saccharomyces cerevisiae preferentially to other yeast enzymes and the rate of inactivation greatly increases in extracts of nitrogen-starved cells. The intensity of inactivation varies for the different synthetases. Under conditions in which more than 80 per cent of the leucyl and isoleucyl-tRNA synthetases are inactivated, the activities of the...
