    • Provided herein are compositions and methods for improving secretion of heterologous protein from a population of Pseudomonas fluorescens-derived cells. The compositions include host cell populations that have been genetically modified to increase secretion into the extracellular space of a heterologous protein of interest. The genetically-modified host cell populations are useful for improving the extracellular secretion of any protein of interest, including therapeutic proteins, hormones, a growth factors, extracellular receptors or ligands, proteases, kinases, blood proteins, chemokines, cytokines, antibodies and the like. In various embodiments, the modified P. fluorescens host cell populations include one or more genomic mutations responsible for or contributing to the improved level of extracellular secretion. The host cell populations of the invention include the modified P. fluorescens strains deposited in the American Type Tissue Culture Collection and assigned accession numbers PTA-8981 and PTA-8982.
    • 本文提供了用于改善来自荧光假单胞菌衍生细胞群的异源蛋白质分泌的组合物和方法。 组合物包括已被遗传修饰以增加分泌到感兴趣的异源蛋白质的细胞外空间中的宿主细胞群体。 遗传修饰的宿主细胞群体可用于改善任何目标蛋白质的细胞外分泌,包括治疗性蛋白质,激素,生长因子,细胞外受体或配体,蛋白酶,激酶,血液蛋白,趋化因子,细胞因子,抗体等 。 在各种实施方案中,经修饰的荧光假单胞菌宿主细胞群体包括负责或有助于提高细胞外分泌水平的一个或多个基因组突变。 本发明的宿主细胞群包括保藏在美国组织培养物保藏中心的经修饰的荧光假单胞菌菌株,并分配了登录号PTA-8981和PTA-8982。

    • The present invention provides shuttle vectors compatible with a panel of different bacterial hosts and capable of replicating in evolutionarily divergent bacterial species. In various embodiments the shuttle vectors of the present invention can integrate into the genomes of and/or replicate in both Gram-negative and Gram-positive organisms of both high and low GC content. The vectors of the present invention therefore make possible the expression of environmental DNA in varied families of bacterial hosts using a single vector that is transferable between hosts by a variety of methods. In some embodiments, the vector can replicate in a genera of bacteria from each of the following groups: Escherichia or Klebsiella; Pseudomonas, Xanthomonas, or Acetobacter; Bacillus or Clostridia, and Corynebacteria, Streptomycete, or Rhodococcus. In various embodiments, the vectors are cosmid, plasmids, fosmids, or bacterial artificial chromosomes (BACs).
    • 本发明提供了与一组不同细菌宿主相容并能够在进化上不同的细菌物种中复制的穿梭载体。 在各种实施方案中,本发明的穿梭载体可以整合到高GC含量和低GC含量的革兰氏阴性和革兰氏阳性生物体的基因组中和/或复制。 因此,本发明的载体可以使用可通过各种方法在宿主之间转移的单一载体在不同的细菌宿主家族中表达环境DNA。 在一些实施方案中,载体可以在来自以下各组的细菌属中复制:埃希氏菌属或克雷伯菌属; 假单胞菌属,黄单胞菌属或醋杆菌属; 芽孢杆菌属或梭菌属,以及棒状杆菌属,链霉菌属或红球菌属。 在各种实施方案中,载体是粘粒,质粒,fosmids或细菌人工染色体(BAC)。
