The Pribnow box (also known as the Pribnow-Schaller box) is the sequence TATAAT of six nucleotides (thymine-adenine-thymine-etc.) that is an essential part of a promoter site on DNA for transcription to occur in bacteria.[1][2] It is an idealized or consensus sequence—that is, it shows the most frequently occurring base at each position in a large number of promoters analyzed; individual promoters often vary from the consensus at one or more positions. It is also commonly called the -10 sequence, because it is centered roughly 10 base pairs upstream from the site of initiation of transcription.
The Pribnow box has a function similar to the TATA box that occurs in promoters in eukaryotes and archaea: it is recognized and bound by a subunit of RNA polymerase during initiation of transcription. This region of the DNA is also the first place where base pairs separate during prokaryotic transcription to allow access to the template strand. The AT-richness is important to allow this separation, since adenine and thymine are easier to break apart (not due to the hydrogen bond count[3]).
It is named after David Pribnow and Heinz Schaller.[1][2]

- Natural IS711 insertion causing omp31 gene inactivation in Brucella ovis.
- Gyuranecz M, Kreizinger Z, Horváth G, Rónai Z, Dán A, Nagy B, Szeredi L, Makrai L, Jánosi S, Hajtós I, Magyar T, Bhide M, Erdélyi K, Dénes B.Author information Institute for Veterinary Medical Research, Hungarian Academy of Sciences, Budapest, Hungary. m.gyuranecz@gmail.comAbstractThe present report describes an atypical Brucella ovis strain (Bo10) isolated from the epididymis and testis of an infected ram. Macroscopic and microscopic lesions characteristic for the infection, including positive Brucella immunostaining, were observed within lesions in the genital organs. Compared to other isolates, strain Bo10 required an additional day (a total of 96 hr) of incubation to form visible colonies, showed a distinct carbon source utilization profile, agglutinated only weakly with rough (R) serum, but showed a high capacity for autoagglutination. Isolate Bo10 failed to produce the 1,071-bp fragment in the outer membrane protein (omp) 31 gene-based part of the "Bruce-ladder" multiplex polymerase chain reaction system but did produce a 1,915-bp amplicon, thus presenting a profile similar to Brucella abortus. Sequence analysis of the 1,915-bp fragment revealed an 842-bp long insertion sequence (IS)711 transposon element inserted into the promoter region of the omp31 gene, immediately upstream from the ribosome binding site (-10 box/Pribnow box). Sodium dodecyl sulfate-polyacrylamide gel electrophoresis of a whole-cell lysate showed the absence in Bo10 of the approximately 31-kDa protein fragment associated with omp31. The results demonstrate a natural inactivation of omp31 and, consequently, the absence of the Omp31 protein in this B. ovis isolate. The novel location of IS711 within the genome of a naturally occurring B. ovis strain supports the hypothesis that IS711 could be an active transposon in this Brucella species.

- Structural and biophysical studies on two promoter recognition domains of the extra-cytoplasmic function sigma factor sigma(C) from Mycobacterium tuberculosis.
- Thakur KG, Joshi AM, Gopal B.Author information Molecular Biophysics Unit, Indian Institute of Science, Bangalore 560012, India.Abstractsigma factors are transcriptional regulatory proteins that bind to the RNA polymerase and dictate gene expression. The extracytoplasmic function (ECF) sigma factors govern the environment dependent regulation of transcription. ECF sigma factors have two domains sigma(2) and sigma(4) that recognize the -10 and -35 promoter elements. However, unlike the primary sigma factor sigma(A), the ECF sigma factors lack sigma(3), a region that helps in the recognition of the extended -10 element and sigma(1.1), a domain involved in the autoinhibition of sigma(A) in the absence of core RNA polymerase. Mycobacterium tuberculosis sigma(C) is an ECF sigma factor that is essential for the pathogenesis and virulence of M. tuberculosis in the mouse and guinea pig models of infection. However, unlike other ECF sigma factors, sigma(C) does not appear to have a regulatory anti-sigma factor located in the same operon. We also note that M. tuberculosis sigma(C) differs from the canonical ECF sigma factors as it has an N-terminal domain comprising of 126 amino acids that precedes the sigma(C)(2) and sigma(C)(4) domains. In an effort to understand the regulatory mechanism of this protein, the crystal structures of the sigma(C)(2) and sigma(C)(4) domains of sigma(C) were determined. These promoter recognition domains are structurally similar to the corresponding domains of sigma(A) despite the low sequence similarity. Fluorescence experiments using the intrinsic tryptophan residues of sigma(C)(2) as well as surface plasmon resonance measurements reveal that the sigma(C)(2) and sigma(C)(4) domains interact with each other. Mutational analysis suggests that the Pribnow box-binding region of sigma(C)(2) is involved in this interdomain interaction. Interaction between the promoter recognition domains in M. tuberculosis sigma(C) are thus likely to regulate the activity of this protein even in the absence of an anti-sigma factor.

- Increased resistance to beta-lactams in a Klebsiella pneumoniae strain: role of a deletion downstream of the Pribnow box in the blaSHV-1 promoter.
- Corvec S, Caroff N, Cosano D, Dauvergne S, Drugeon H, Reynaud A.Author information Laboratoire de Bactériologie-Virologie, Hygiène Hospitalière, CHU de Nantes, 9 quai Moncousu, 44093 Nantes Cedex 01, France. stephane.corvec@chu-nantes.frAbstractTwo hundred and five isolates of Klebsiella pneumoniae were collected from Nantes University Hospital in 2002. A new 30bp deletion was detected downstream of the -10 box of the SHV-1 promoter in a clinical K. pneumoniae isolate with a high amoxicillin/clavulanic acid minimum inhibitory concentration. Reverse transcription polymerase chain reaction revealed increased transcription of bla(SHV-1) mRNA. All conjugation mating assays failed. This new promoter was cloned upstream of the cat gene of the reporter plasmid pKK232-8 and compared with previously described bla(SHV-1) promoters. The deletion induced a 15-fold increase in promoter strength compared with the usual weak promoter. This study reports a new genetic event that increases bla(SHV-1) chromosomal gene expression, which may be of clinical relevance when associated with porin deficiency.
