title: [Nourseothricin (streptothricin) inactivated by plasmid pIE 636-encoded acetyltransferase: detection of N-acetyl-beta-lysine in the inactivated product].
abstract: Nourseothricin (streptothricin) can be inactivated by an acetyl transferase synthesized by E. coli strains containing plasmid pIE 636. Nourseothricin inactivated in the presence of 14C-acetyl-coenzyme A was purified and submitted to partial acidic hydrolysis. By electrophoresis of the hydrolysate a 14C-containing substance moving only slowly towards the cathode could be isolated. This substance after complete hydrolysis yields only unlabelled beta-lysine.
