Overlapping mRNA transcripts of photosynthesis gene operons in Rhodobacter capsulatus.

abstract：:Previous microarray studies have suggested that an indirect mechanism of Fur regulation may be present in meningococcus at the posttranscriptional level through a small regulatory RNA (sRNA) system analogous to that of Escherichia coli and Pseudomonas aeruginosa. Recently, a Fur-regulated sRNA, NrrF, was identified th...
