Pathway integration and expression in host cells

Provided herein are methods for integrating a gene of interest into a chromosome of a host cell. In some embodiments, the methods include introducing into a host cell a first plasmid comprising a transposase coding sequence and a donor sequence, which includes a selectable marker coding sequence flanked by a first and a second lox site and is itself flanked by inverted repeats recognized by the transposase. Following transposase-mediated chromosomal integration of the donor sequence into the host cell, a second plasmid is introduced, which comprises the gene of interest and a second selectable marker coding sequence, both flanked by a first and a second lox site. The gene of interest is chromosomally integrated into the host cell by recombinase-mediated cassette exchange (RMCE) between the donor sequence and the second plasmid via Cre-/cuc recombination. Further provided herein are host cells, vectors, and methods of producing a product related thereto.

Periplasmic fusion proteins

Periplasmic fusion proteins comprising a binding motif attached to a C-terminus of a first protein or embedded within an amino acid sequence of the first protein, nucleic acid constructs encoding the periplasmic fusion proteins, vectors comprising the nucleic acid constructs, and methods of producing the periplasmic fusion proteins are provided. Also provided are protease deficient host cells for producing the periplasmic fusion proteins.
