Abstract excerpt
Among the known functions of the P(II) protein (the glnB gene product) in the cyanobacterium Synechococcus elongatus, negative regulation of the activity of PipX, a transcriptional co-activator of the NtcA regulon, has been thought to be essential for cell viability, because all the P(II)-less mutants thus far constructed carry spontaneous mutations in pipX. PipX is thus deduced to be a toxic protein, but its...
