Note(s): | The unusual rpsU-dnaG-rpoD operon, conserved in different gram-negative bacteria, participates in macromolecular synthesis Versalovic J, Koeuth T, Britton R, Geszvain K, Lupski JR,1993 The rpsU gene encodes the S21 protein, which is a component of the 30S subunit of the ribosome, the dnaG gene encodes a DNA primase that catalyzes the synthesis of RNA primers on single-stranded template DNA, and the rpoD gene encodes the primary σ factor that plays the most important role in promoter regulation during exponential growth (σ70). As it can be seen, this operon comprises three essential genes, whose products represent each of the three different main cellular molecules (RNA, DNA, and protein). In this way, this operon comprises three existing information fluxes of the central dogma of molecular biology, and its products participate in indispensable functions: in the initiation of protein synthesis (S21) and RNA synthesis from different templates (DNA primase, single strand; σ70, double strand) Versalovic J, Koeuth T, Britton R, Geszvain K, Lupski JR,1993. Burton ZF,1983 The coordinated expression of this operon is dependent on three tandem promoters, P1, P2, and P3, which are activated under different conditions Lupski JR,1984. Nesin M, Lupski JR, Godson GN,1988 However, the expression of individual rpsU and rpoD genes can be independently regulated by their own promoters. About the end of the operon, there are two terminators, an internal terminator (T1) in the intergenic region between the rpsU gene and dnaG gene and a rho-independent terminator at the end of the operon (T2). The internal terminator might respond to antitermination by the lambda phage N gene product. |

Note(s): | rpsUp2 has a sequence similar to that of a number of promoters under stringent control. Transcription initiation from rpsUDp2 and rpsUDp3 allows for greater readthrough at the internal terminator T2, thus increasing the relative ratio of dnaG and rpoD. rpsUp2 overlaps rpsUp3. It possible that another promoter with a transcriptional start site at positions 3210716/7/8 transcribes the rpsU-dnaG-rpoD operon, as determined by high-throughput screening of maps of promoters Lacoux C,2020. |
