  FimZ Binds theSalmonella typhimurium fimAPromoter Region and May Regulate Its Own Expression with FimY

  摘要：

  AbstractThe FimZ protein, an activator of FimA production in Salmonella typhimurium, acts in conjunction with FimY to facilitate the expression of type 1 fimbriae. The predicted amino acid sequence of FimZ suggests that this protein may be a DNA‐binding protein related to BvgA, a sensory regulator of virulence gene expression in Bordetella pertussis. Purification of FimZ following overexpression of the protein by a strong inducible promoter and gel mobility shift assays confirm that FimZ is a 25‐kDa polypeptide that binds to the promoter region of fimA. The region of DNA protected from DNase I digestion by FimZ binding is located between 47 and 98 nucleotides upstream from the fimA transcription initiation site. This region possesses a pair of 7‐base pair tandem repeats, of which at least one is necessary for FimZ binding. One copy of the 7‐base pair sequence is also located in the fimZ promoter region. In addition, expression from a fimZ‐lacZ reporter construct confirms that FimZ plays a role in its own expression. Both FimZ and FimY are required for high‐level expression of FimZ, which suggests that these two fimbrial proteins are involved in regulating both FimA and FimZ.

  The scope of the utility of diphenylvinylphosphine ligands has been extended to include the Suzuki-Miyaura coupling reaction. A catalyst composed of phosphines and palladium efficiently mediates the reactions of a variety of aryl halides with arylboronic acids to afford the corresponding biphenyls in good to excellent yields.

• The preparation of some 1,7b-disubstituted cyclopropa[c]isoquinolines via nitrile ylide cyclisations and their rearrangement to 2-benzazepines and 4-alkenyl-1,4-dihydroisoquinolines

  Diene-conjugated nitrile ylides of the type 1a, having substituents other than hydrogen in the R1 position, cyclise normally to give the C-7b substituted cyclopropa[c]isoquinolines 2a. In cases where R2 or R3 = H the latter undergo the usual thermal rearrangement to give 5-substituted 2-benzazepines 5a. However, when R2 and R3 ≠ H and either is a CH3 group, then the presence of the C-7b substituent

  在R 1位置具有除氢以外的取代基的类型为1a的二烯共轭腈，通常会环化生成C-7b取代的环丙烷[ c ]异喹啉2a。在R 2或R 3  ＝ H的情况下，后者进行通常的热重排，得到5-取代的2-苯并ze庚因5a。然而，当R 2和R 3  ≠H且均为CH 3基团时，则2a中C-7b取代基的存在会将热重排转移到新的反应路径上，从而导致形成1,4-二氢-4 -烯基异喹啉14高产。
