Abstract: Rediced genome or native K12 strain E. coli bacteria comprising expression vectors encoding a recombinant CRM197 protein and their use in the production of CRM 197 is provided. The CRM 197 protein may be fused to a signal sequence that directs the expressed CRM197 protein to the periplasm of the E. coli host.

Abstract: E. coli bacteria comprising genetic modifications to enhance fermentability and production of protein and nucleic acids are provided.

Abstract: A triple host vector is described which is capable of expressing an inserted protein coding DNA sequence in any of three distinct host systems. The vector includes three promoters, one each for vertebrate, bacterial and insect host cells, so that the protein coding sequence can be cloned into the vector once and the vector can be used to express protein in all three types of host cells. The arrangement and selection of the promoters contributes to expression characteristics in all three host systems that is comparable to single host expression vectors.

Abstract: A vector for the direct cloning of the products of PCR protocol incorporates single nucleotide overhangs at one or both ends of a linearized DNA segment. The single nucleotide overhangs are uracil or inosine residues, as desired, to facilitate cloning of the desired PCR products.
