Threonyl-tRNA synthetase from Chinese hamster ovary cells is phosphorylated on serine.

Abstract

A Chinese hamster ovary cell line, 2000A, in which threonyl-tRNA synthetase accounts for 1.5% of the total soluble protein, was used to demonstrate that this enzyme is a phosphoprotein. Threonyl-tRNA synthetase was isolated by immunoprecipitation from cells labeled with 32Pi for 18 h. Phosphoamino acid analysis of radiolabeled threonyl-tRNA synthetase… (More)
