Bovine tryptophanyl-tRNA synthetase--a zinc metalloenzyme

As is found by atomic absorption spectroscopy, the highly purified bovine tryptophanyl-tRNA synthetase contains up to 0.9 mol Zn2+/mol enzyme while some other bivalent metal ions are absent. The enzyme is inactivated either upon treatment with 1,10-phenanthroline (a zinc-chelating agent) or upon pro...
