32P-labeling of bovine tryptophanyl-tRNA synthetase with [32P]pyrophosphate
Copyright policy )32P-labeling of bovine tryptophanyl-tRNA synthetase with [32P]pyrophosphate
The covalent derivative of the tryptophanyl-tRNA synthetase obtained under the action of32PPi contains one mole of the covalently bound pyrophosphate (or 2 moles of orthophosphate) per mole of dimeric enzyme. Dephosphorylation with alkaline phosphatase causes practically no changes of enzymatic activity although the enzyme looses its ability to bind PPi.
