    Official Symbol
    suhB
    Official Full Name
    Nus factor SuhB
    Primary source
    ECOCYC:EG10983
    Locus tag
    b2533
    Gene type
    protein coding
    RefSeq status
    PROVISIONAL
    Organism
    Escherichia coli str. K-12 substr. MG1655 (strain: K-12, substrain: MG1655)
    Lineage
    Bacteria; Pseudomonadota; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia
    Also known as
    ECK2530; ssyA
    Summary
    The N-terminal sequence was determined using protein made with a synthetic RBS, and thus is not a confirmation of the in vivo start site; the N-terminal Met was not clipped off the recombinant protein. [More information is available at EcoGene: EG10983]. The suhB gene has been shown to encode a protein with inositol monophosphatase and glycerol-2-phosphatase activity . [More information is available at EcoCyc: EG10983].

    2. SuhB can be integrated into a Nus factor-, and optionally ribosomal protein S4-, containing antitermination complex halted at a ribosomal antitermination signal. Furthermore, SuhB specifically binds to the acidic repeat 2 domain of the multi-domain protein NusA, an interaction that may be involved in antitermination or posttranscriptional processes.
      Title: SuhB is an integral part of the ribosomal antitermination complex and interacts with NusA.
    3. Results reveal functions of SuhB during ribosomal RNA synthesis and delineate some of the underlying molecular interactions.

    4. The authors demonstrate that the main function of this SuhB-containing complex is not to prevent premature transcription termination within the rRNA operon, as had been long claimed, but to enable rRNA maturation and a functional ribosome fully competent for translation.
