Aeration-dependent changes in composition of the quinone pool in Escherichia coli. Evidence of post-transcriptional regulation of the quinone biosynthesis

FEBS Lett. 1997 Mar 10;404(2-3):272-4. doi: 10.1016/s0014-5793(97)00143-9.

Abstract

The aeration-dependent changes in content of various quinones in Escherichia coli were found to be unaffected by a prokaryotic translation inhibitor chloramphenicol. In addition, this process was shown to be completely intact in cells with mutated fnr, arc and appY loci. It is assumed that E. coli possesses a special system of oxygen-dependent post-transcriptional regulation of the quinone biosynthetic pathways.
