摘要
Puromycin led either to stimulation or to inhibition of phenylalanine incorporation in cell-free systems from Bacillus licheniformis and Bacillus stearothermophilus 10. Stimulation was observed at low puromycin concentrations, at high puromycin concentrations in the presence of excess transfer RNA, and over a narrow range of temperatures. Inhibition was observed at high puromycin concentrations and at temperatures below and above the range where stimulation occurred. Freshly prepared subcellular fractions were inhibited to a greater extent than stored fractions. © 1969.
