    摘要: Recombinant lentiviral vectors containing at least: a lentiviral backbone comprising essential lentiviral sequences for integration into a target cell genome; a nucleic acid encoding a CCR5 RNAi; and an expression control element that regulates expression of the nucleic acid encoding the CCR5 RNAi element, are provided by this invention. In an alternative aspect, the vector also contains polynucleotides encoding TRIM5 alpha and HIV TAR decoy sequences along with gene expression regulation elements such as promoters operatively linked to the polynucleotides. The vectors are combined with packaging plasmid and envelope plasmids and optionally conjugated to cell-specific targeting antibodies. Diagnostic and therapeutic methods for using the compositions are further provided herein.

    摘要: The biosynthesis of fungal bicyclo[2.2.2]diazaoctane indole alkaloids with a wide spectrum of biological activities have attracted increasing interest. Their intriguing mode of assembly has long been proposed to feature a non-ribosomal peptide synthetase, a presumed intramolecular Diels-Alderase, a variant number of prenyltransferases, and a series of oxidases responsible for the diverse tailoring modifications of their cyclodipeptide-based structural core. Until recently, the details of these biosynthetic pathways have remained largely unknown due to lack of information on the fungal derived biosynthetic gene clusters. Herein, we report a comparative analysis of four natural product metabolic systems of a select group of bicyclo[2.2.2]diazaoctane indole alkaloids including (+)/(−)-notoamide, paraherquamide and malbrancheamide, in which we propose an enzyme for each step in the biosynthetic pathway based on deep annotation and on-going biochemical studies.

    摘要: An object of the present invention is to provide a protein having dipeptide synthesizing activity with improved substrate specificity, and a method in which the protein or a microorganism having ability to produce the protein is used to efficiently produce a target dipeptide while reducing a by-product dipeptide produced in addition to the target dipeptide. According to the present invention, a protein consisting of an amino acid sequence obtained by substituting, with other amino acid residues, amino acid residues corresponding to one or more amino acid residues selected from the group consisting of amino acid residues at positions 107, 108, and 110 in an amino acid sequence set forth in SEQ ID NO: 2, or a mutant protein or a homologous protein of a protein consisting of the amino acid sequence set forth in SEQ ID NO: 2 is provided, and a microorganism producing the protein can be used to efficiently produce a dipeptide.
