nusA | nusG | Z4530 | Z5555 | Transcription pausing; Participates in both transcription termination and antitermination. | Component in transcription antitermination; Participates in transcription elongation, termination and antitermination. In the absence of Rho, increases the rate of transcription elongation by the RNA polymerase (RNAP), probably by partially suppressing pausing. In the presence of Rho, modulates most Rho-dependent termination events by interacting with the RNAP to render the complex more susceptible to the termination activity of Rho. May be required to overcome a kinetic limitation of Rho to function at certain terminators. Also involved in ribosomal RNA transcriptional antitermination [...] | 0.975 |
nusA | pnp | Z4530 | Z4525 | Transcription pausing; Participates in both transcription termination and antitermination. | Polynucleotide phosphorylase; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction. | 0.876 |
nusA | rfaH | Z4530 | Z5362 | Transcription pausing; Participates in both transcription termination and antitermination. | Transcription antitermination protein RfaH; Enhances distal genes transcription elongation in a specialized subset of operons that encode extracytoplasmic components. RfaH is recruited into a multi-component RNA polymerase complex by the ops element, which is a short conserved DNA sequence located downstream of the main promoter of these operons. Once bound, RfaH suppresses pausing and inhibits Rho-dependent and intrinsic termination at a subset of sites. Termination signals are bypassed, which allows complete synthesis of long RNA chains. | 0.785 |
nusA | rho | Z4530 | Z5293 | Transcription pausing; Participates in both transcription termination and antitermination. | Transcription termination factor Rho; Facilitates transcription termination by a mechanism that involves Rho binding to the nascent RNA, activation of Rho's RNA- dependent ATPase activity, and release of the mRNA from the DNA template. | 0.898 |
nusA | rpoA | Z4530 | Z4665 | Transcription pausing; Participates in both transcription termination and antitermination. | RNA polymerase, alpha subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. | 0.998 |

nusA | rpoZ | Z4530 | Z5075 | Transcription pausing; Participates in both transcription termination and antitermination. | RNA polymerase, omega subunit; Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits (By similarity). | 0.895 |
nusA | rpsA | Z4530 | Z1257 | Transcription pausing; Participates in both transcription termination and antitermination. | 30S ribosomal subunit protein S1; Required for translation of most natural mRNAs except for leaderless mRNA. Binds mRNA upstream of the Shine-Dalgarno (SD) sequence and helps it bind to the 30S ribosomal subunit; acts as an RNA chaperone to unfold structured mRNA on the ribosome but is not essential for mRNAs with strong SDs and little 5'-UTR structure, thus it may help fine-tune which mRNAs that are translated. Unwinds dsRNA by binding to transiently formed ssRNA regions; binds about 10 nucleotides. Has a preference for polypyrimidine tracts. Negatively autoregulates its own translation. | 0.948 |
